It was sitting at ~$8000 for quite a while (down from a launch price of $20,000). The recent hot deals are very recent. Interestingly, the T221's almost-identical competitor from Viewsonic (uses the same panel) which has historically been ~20% cheaper at the discount places than the T221, is actually more expensive now.
Shark cartilage has indeed been rejected as a possible treatment for cancer.

Sharks: a potential source of antiangiogenic factors and tumor treatments. Cho J, Kim Y. Department of Microbiology, Pukyong National University, Pusan 608-737, Korea.
Since angiogenesis is a key feature of tumor growth, inhibiting this process is one way to treat cancer. Cartilage is a natural source of material with strong antiangiogenic activity. This report reviews knowledge of the anticancer properties of shark cartilage and clinical information on drugs such as neovastat and squalamine. Because their entire endoskeleton is composed of cartilage, sharks are thought to be an ideal source of angiogenic and tumor growth inhibitors. Shark cartilage extract has shown antiangiogenic and antitumor activities in animals and humans. The oral administration of cartilage extract was efficacious in reducing angiogenesis. Purified antiangiogenic factors from shark cartilage, such as U-995 and neovastat (AE-941), also showed antiangiogenic and antitumor activity. AE-941 is under phase III clinical investigation. Squalamine, a low molecular weight aminosterol, showed strong antitumor activity when combined with chemotherapeutic materials. The angiogenic tissue inhibitor of metalloprotease 3 (TIMP-3) and tumor suppressor protein (snm23) genes from shark cartilage were cloned and characterized.

We can probably do it for $100/kg (vs. current uranium prices of $30/kg -- not much of a price difference to worry about since uranium cost is a tiny portion of total nuclear energy cost).

Firstly, uranium (any isotope) is a heavy metal and for that reason tends to be toxic to the kidneys beyond certain dosages.
Secondly, kidney toxicity, from any cause, is radically reduced when the owner of the kidney(s) injests antioxidants that operate in the kidneys. There are many, such as alpha lipoic acid. (ALA reduces damage from metals all over the body, BTW, not just in the kidneys.)

A small group of Gulf War veterans possess retained fragments of depleted uranium (DU) shrapnel, the long-term health consequences of which are undetermined. We evaluated the clinical health effects of DU exposure in Gulf War veterans compared with nonexposed Gulf War veterans. History and follow-up medical examination were performed on 29 exposed veterans and 38 nonexposed veterans. Outcome measures employed were urinary uranium determinations, clinical laboratory values, and psychiatric and neurocognitive assessment. DU-exposed Gulf War veterans with retained metal shrapnel fragments are excreting elevated levels of urinary uranium 7 years after first exposure (range 0.01-30.7 microg/g creatinine vs 0.01- 0.05 microg/g creatinine in the nonexposed). The persistence of the elevated urine uranium suggests on-going mobilization from a storage depot which results in a chronic systemic exposure. Adverse effects in the kidney, a presumed target organ, are not present at this time, though other effects are observed. Neurocognitive examinations demonstrated a statistical relationship between urine uranium levels and lowered performance on computerized tests assessing performance efficiency. Elevated urinary uranium was statistically related to a high prolactin level (>1.6 ng/ml; P=0.04). More than 7 years after first exposure, DU-exposed Gulf War veterans with retained metal fragments continue to excrete elevated concentrations of urinary uranium. Effects related to this are subtle perturbations in the reproductive and central nervous systems. Copyright 2000 Academic Press. PMID: 10662531

The Persian Gulf War resulted in injuries of US Coalition personnel by fragments of depleted uranium (DU). Fragments not immediately threatening the health of the individuals were allowed to remain in place, based on long-standing treatment protocols designed for other kinds of metal shrapnel injuries. However, questions were soon raised as to whether this approach is appropriate for a metal with the unique radiological and toxicological properties of DU. The Armed Forces Radiobiology Research Institute (AFRRI) is investigating health effects of embedded fragments of DU to determine whether current surgical fragment removal policies remain appropriate for this metal. These studies employ rodents implanted with DU pellets as well as cultured human cells exposed to DU compounds. Results indicate uranium from implanted DU fragments distributed to tissues far-removed from implantation sites, including bone, kidney, muscle, and liver. Despite levels of uranium in the kidney that were nephrotoxic after acute exposure, no histological or functional kidney toxicity was observed. However, results suggest the need for further studies of long-term health impact, since DU was found to be mutagenic, and it transformed human osteoblast cells to a tumorigenic phenotype. It also altered neurophysiological parameters in rat hippocampus, crossed the placental barrier, and entered fetal tissue. This report summarizes AFRRI's depleted uranium research to date.

To determine clinical health effects in a small group of US Gulf War veterans (n = 50) who were victims of depleted uranium (DU) "friendly fire," we performed periodic medical surveillance examinations. We obtained urine uranium determinations, clinical laboratory values, reproductive health measures, neurocognitive assessments, and genotoxicity measures. DU-exposed Gulf War veterans with retained metal shrapnel fragments were excreting elevated levels of urine uranium 8 years after their first exposure (range, 0.018 to 39.1 micrograms/g creatinine for DU-exposed Gulf War veterans with retained fragments vs 0.002 to 0.231 microgram/g creatinine in DU exposed but without fragments). The persistence of the elevated urine uranium suggests ongoing mobilization from the DU fragments and results in chronic systemic exposure. Clinical laboratory outcomes, including renal functioning, were essentially normal. Neurocognitive measures showing subtle differences between high and low uranium exposure groups, seen previously, have since diminished. Sister chromatid exchange frequency, a measure of mutation in peripheral lymphocytes, was related to urine uranium level (6.35 sister chromatid exchanges/cell in the high uranium exposure group vs 5.52 sister chromatid exchanges/cell in the low uranium exposure group; P = 0.03). Observed health effects were related to subtle but biologically plausible perturbations in central nervous system function and a general measure of mutagen exposure. The findings related to uranium's chemical rather than radiologic toxicity. Observations in this group of veterans prompt speculation about the health effects of DU in other exposure scenarios.

There may be a perfectly simple solution for this: allow him to see again.
Depending on the type of damage he sustained from the accident, he might be able to see the output from a retinal scanning display perfectly clearly. No focusing is necessary, as it paints the image directly on the retina. If his retinas are not damaged, it will work perfectly. If his retinas have _some_ damage but not total, it will still work to a degree. Beta units are around $8,000 -- well worth it.
If this is not an option, emacspeak is the road down which he should travel. Emacspeak was written entirely from scratch by a totally blind man, T.V. Raman. It works. Get it and set it up for him.

Yes, thankyou, but I still don't know which measurment scale is used:) A person with an IQ of 153 on Cattel has an IQ of "only" 135 on Stanford-Binet;) (Text repeated here because of moderation abuse. --Chris)
Cattell and Stanford-Binet are not measurement scales. IQ tests are normed to various standard deviations. The usual SD is 15 points and they all use a mean, as far as I'm aware, of 100. The Stanford-Binet is normed to an SD of 15 and the Cattell is normed to an SD of 24 (so IQ 124 on the Cattell = IQ 115 on the Stanford-Binet; both of those scores mean your raw test score is above exactly 84.13% of those of the sample population because both of these scores mean your raw score is exactly one standard deviation above the mean).
Since the table of national average IQs Richard Lynn published in his book, _IQ and the Wealth of Nations_, uses a mean of 100 points and a standard deviation of 15 points (i.e. the SD Stanford-Binet tests are normed to), the difference between the national average IQ in Belgium (100 points) and the national average IQ in Slovenia (95 points) is 1/3 standard deviation.
This means there is very little difference in numbers of average IQ (IQ 100) citizens between the two nations. The average Belgian has an IQ higher than that of 50% of the world population -- the average Slovenian has an IQ higher than that of 38% of the world population. 50% of Belgians have an IQ above the world average -- 38% of Slovenians have an IQ above the world average.
These are not important differences. The important differences lie towards the high and low scoring extremes of the populations. The most capable members of the world population are those who score 3 standard deviations (IQ 145 on the Stanford-Binet) or higher above the world mean. 0.13% of Belgian score this high or higher while only 0.05% of Slovenics score this high or higher. These highly capable Belgians outnumber their equally highly capable Slovenian compatriats (per-capita-wise) by a ratio of over 5 to 2 (a bit more than 5 highly capable Belgians for every 2 highly capable Slovenians -- if we draw equally sized random samples from the two populations).
This extreme difference in numbers of highly capable persons per equal unit of population could be an important factor in explaining the difference any differences in technological advancement between the two nations.
Here in Belgium government is serious about e-government. As from next year, businesses will be able to file tax returns via the web. We already can contact government officials *and* get an answer (most of the time, anyway). A lot of official law-related stuff (including new law publishing) is done via the web. Some government contracting is done via e-commerce.

Adverse effects in the kidney, a presumed target organ, were not seen at the time of the study; however, other subtle effects were observed in the reproductive and central nervous systems of the DU-exposed veterans.

1GB of RAM consumes about 5-10 watts. 1GB of hardrive has negligable power consumption in comparison.

Schools also should not be the ones teaching these things. Kids can learn them on their own. I did. They do not, in any way, aid teaching.
Education tax dollars not spent on schools can be instead dolled out directly to the students to spend as they please. An efficient way to do this would be to cancel all school taxes and let the parents fund their children's educations directly.

Scientists in Africa, for the betterment of the world, would best be encouraged to leave. Their talents would be better spent in a country that can use those talents -- a country like the USA.
The following are the average IQ's of the polulations of sub-Saharan African nations. The upper limit for mental retardation is IQ 85. Every sub-Saharan African nation's population has an average IQ below this threshold:
Zambia 77
Congo (Brazz)73
Uganda 73
Jamaica 72
Kenya 72
South Africa 72
Sudan 72
Tanzania 72
Ghana 71
Nigeria 67
Guinea 66
Zimbabwe 66
Congo (Zaire)65
Sierra Leone 64
Ethiopia 63
Equat. Guinea59
These are not developing nations. They are incapable of developing. These nations can contribute nothing to the information economy and those few talented individuals who live in them would be helping themselves and the world if they would leave for a nation with a modern infrastructure that can support the kind of work they are capable of.

There may be a perfectly simple solution for this: allow him to see again.
Depending on the type of damage he sustained from the accident, he might be able to see the output from a retinal scanning display perfectly clearly. No focusing is necessary, as it paints the image directly on the retina. If his retinas are not damaged, it will work perfectly. If his retinas have _some_ damage but not total, it will still work to a degree. Beta units are around $8,000 -- well worth it.
If this is not an option, emacspeak is the road down which he should travel. Emacspeak was written entirely from scratch by a totally blind man, T.V. Raman. It works. Get it and set it up for him.

Yes, thankyou, but I still don't know which measurment scale is used
Cattell and Stanford-Binet are not measurement scales. IQ tests are normed to various standard deviations. The usual SD is 15 points and they all use a mean, as far as I'm aware, of 100. The Stanford-Binet is normed to an SD of 15 and the Cattell is normed to an SD of 24 (so IQ 124 on the Cattell = IQ 115 on the Stanford-Binet; both of those scores mean your raw test score is above exactly 84.13% of those of the sample population because both of these scores mean your raw score is exactly one standard deviation above the mean).
Since the table of national average IQs Richard Lynn published in his book, _IQ and the Wealth of Nations_, uses a mean of 100 points and a standard deviation of 15 points (i.e. the SD Stanford-Binet tests are normed to), the difference between the national average IQ in Belgium (100 points) and the national average IQ in Slovenia (95 points) is 1/3 standard deviation.
This means there is very little difference in numbers of average IQ (IQ 100) citizens between the two nations. The average Belgian has an IQ higher than that of 50% of the world population -- the average Slovenian has an IQ higher than that of 38% of the world population. 50% of Belgians have an IQ above the world average -- 38% of Slovenians have an IQ above the world average.
These are not important differences. The important differences lie towards the high and low scoring extremes of the populations. The most capable members of the world population are those who score 3 standard deviations (IQ 145 on the Stanford-Binet) or higher above the world mean. 0.13% of Belgian score this high or higher while only 0.05% of Slovenics score this high or higher. These highly capable Belgians outnumber their equally highly capable Slovenian compatriats (per-capita-wise) by a ratio of over 5 to 2 (a bit more than 5 highly capable Belgians for every 2 highly capable Slovenians -- if we draw equally sized random samples from the two populations).
This extreme difference in numbers of highly capable persons per equal unit of population could be an important factor in explaining the difference any differences in technological advancement between the two nations.

Here in Belgium government is serious about e-government. As from next year, businesses will be able to file tax returns via the web. We already can contact government officials *and* get an answer (most of the time, anyway). A lot of official law-related stuff (including new law publishing) is done via the web. Some government contracting is done via e-commerce.
Well, it's no wonder. You Belgians have a 5 point average IQ advantage over the Slovenians. (Scroll down to see country IQ table.)
Belgian average IQ: 100
Slovenian average IQ: 95
