    That's a big assumption. There is a well known effect called 'winner's curse' relating to auction based pricing. Wikipedia summaries:

    In a common value auction, the auctioned item is of roughly equal value to all bidders, but the bidders don't know the item's market value when they bid. Each player independently estimates the value of the item before bidding. The winner of an auction is, of course, the bidder who submits the highest bid. Since the auctioned item is worth roughly the same to all bidders, they are distinguished only by their respective estimates. The winner, then, is the bidder making the highest estimate. If we assume that the average bid is accurate, then the highest bidder overestimates the item's value. Thus, the auction's winner is likely to overpay.

    No. The real problem is that FCC has only made a very small, very expensive allocations to GSM use. The equipment can support many more channels but the frequencies are legally limited in the US. Thus why bandwidth is bad here and much better elsewhere. Ditto for cost concerns. Wireless carriers have paid a lot of more at auction to the US Government than similar allocations cost in other countries.

    See for instance this recent article at the wsj

    The FCC has approved a threefold increase in available spectrum in recent years, but projections for data traffic show a 30-fold increase in demand, Mr. Genachowski said. "That's a 10-to-one gap," he said. "It's a very serious challenge."

    ...

    Wireless industry lobbyists have spent months trying to persuade lawmakers to pass legislation that would require the government to do an inventory of the U.S.'s airwaves and how they are being used. The U.S. government controls much of the available airwaves, which are set aside for military and other official uses. Rights to airwaves are auctioned off to companies to use exclusively.

    Mr. Genachowski said the FCC would look at ways to promote secondary markets for airwaves, which would give people who hold licenses for airwave usage the right to lease those licenses to others. He said the agency would also try to clear obstacles for wireless companies trying to install new networks, including speeding up approvals for new cellphone tower construction, which often are met with community resistance.

    "The Bounty's log shows that Bligh resorted to punishments relatively sparingly. He scolded when other captains would have whipped and whipped when other captains would have hanged. He was an educated man, deeply interested in science, convinced that good diet and sanitation were necessary for the welfare of his crew. He took a great interest in his crew's exercise, was very careful about the quality of their food, and insisted upon the Bounty being kept very clean."

    Its a sad that you got mod-points for your ad hominem drivel.

    Christy and Spencer have stated repeatedly in the scientific literature that they their analysis of radiosonde data agrees CLOSELY WITH THOSE OF OTHER SCIENTISTS

    This is a red herring. UAH and RSS agree very closely, so what? That is not the issue raised by any of the four comments I linked to. There is no reason to doubt the UAH/RSS temperature series.

    Christy is one of the authors of NOAA's Climate Change Science Program report that clearly states that global warming is real and man-made. Yet, he is more than happy to take money from the ExxonMobil funded Heartland institute and say global warming doesn't exist

    His comment submission to the EPA particularly discusses how the CCSP report was politicized--that its conclusions were not supported by the available science.

    McIntyre cann't even use someone elses data and programs correctly. He tried to replicate Mann's hockey stick, but made so many mistakes that the National Research Council had to publish it's own analysis that demonstrated McIntyres errors and reaffirmed Mann's work. ten other independent groups have been able to duplicate Mann's work and show that Mann was too conservative in his findings.

    Although the obscurity of the MBH methodology (as applied) lead to some inconsistencies, McIntyre did not fail to use "someone elses programs and data correctly." Rather Mann failed to document and describe his scientific procedure in a thorough and appropriate fashion.

    The NRCs work was subsequently reviewed by congressional committee and an independent statistician which led to the 'Wegman report'. The latter analysis supersedes the NRC and validates McIntyre's work and discredits the line of MBH papers.

    I've personally looked at Mann's method and McIntyre's criticisms. Coming from a machine-learning background, Mann's methodology is clearly prone to 'overfit' and data-mining. To wit, the simple explanation is that he used 100 years (points) of calibration against ~120 time-series. Now any arbitrary linear weighting of those time-series is likely to produce a flat, trendless signal. During the calibration period--which uses 20th century temperature data that is basically trendless until 1980 followed by an increase in temperature, he fitted the time-series in linear combination to reproduce this curve (minimize rms error). This is basically just a question of having adequate free-variables to adjust the data to fit, but outside of the calibration interval the weightings are essentially arbitrary.

    Thus his result: several hundred years of trendless temperature followed a curve that looks like the 20th century. From this he concluded that the 20th century temperature change was unprecedented. This conclusion using this method is patently fatuous.

    Glossy is a bug, not a feature.

    Actually glossy is a superior technology for imaging hobbled by having only 8bits per color channel. Similar problems have arisen with wide-gamut displays. 8bit precision means fairly coarse steps between shades as the range of reproducible colors (gamut) increases. Glossy screens have better color gamut because environmental light contributes less "white pollution" because most sources are reflected away, not toward the viewer. Using a matte screen is more like looking through a layer of milk. Your mind's eye sees around the matte effect because of its uniformity across the screen, whereas residual reflections are distinctly localized in the glossy case.

    Now people doing press work actually cannot use the expanded gamut of the glossy screen--because paper is a limited medium. Therefore, given the bit-depths available, they prefer the more limited reproduction of a matte screen.

    To put this in perspective: The gold-standard for imaging is historically CRT technology which shares similar glossy properties.

    Extreme brightness on glossy displays = extreme contrast. It's harder to believe you're looking at a calibrated 2.2 gamma when your "superbrite" glossy LCD display has such a massive contrast ratio.

    Contrast has nothing what so ever do with gamma. A CRT has a contrast ratio in the 10000-100000:1 range.

    Working in neutrally-painted, darkened rooms is optimal. When you turn these superbright LCDs down to achieve a reasonable brightness for a darkened room, the glare and reflections from the glossy panel are distracting. Turn it back up, and it takes you several seconds to a minute to see where you're going.

    Glossy LCDs use coatings which originated with CRTs. Its the same technology evolved. A CRT and a glossy LCD have similar glare properties. If you clients are having glare problems, they need to be using a hood.

    The higher brightness leads to colors looking more saturated, which sells with consumers.

    Glossy screens are not any brighter than matte. Their contrast comes from having a better black-level, i.e., less diffuse glare from the environment. "Color saturation" is how much "white" is mixed into color. Matte screens have worse saturation because they mix in (diffuse) more environmental "white" light.

    Photographers who rely on a muted palette and who work in color managed workflows can't tell what's going to roll out of their printer with displays like the iMac's glossy LED display - the colors seem too contrasty and saturated, so everything gets dialled down too far.

    This point is the closest to being right. Glossy screens have a more different color-space relative to CYMK ink processes than matte screens. But any good software, such as photoshop, has the ability to highlight gamut errors. The remaining trouble is that the in gmaut color-space is compressed because the display's color-space is larger.

    The real problem is that 8b/color channel is not enough for modern wide-gamut displays such those you can make using LED backlights and glossy anti-glare coatings. Photographers near universal failure to understand the technical situation and speak-up means that their needs are wholly under-represented, and many of the new color-professional wide-gamut products are unusable due the colorimetric distances being too far given 8b/color channel.
