Finding a row in an indexed table is at least as fast as finding a file in a directory. Most network DB connections involve converting binary data to string, but that is only a constant factor in space/performance. Your assertion that reading a file is really an order of magnitude faster than reading a row from an indexed table is dubious at best.

the location of symbols on dvorak is not significantly different from querty. some of them are easier to reach, esp. english puncuation like comma, period, dash, quotes. I find the semicolon very easy to reach as well, it is the querty "Z" key.
I would guess that in a contest of typing only symbols, dvorak would win because it spreads more of them out, i.e. assigns some to each hand so the load is more balanced (there is a speed advantage as well since one hand can prepare for the next while the other is still executing the current).

iaudio (aka cowon) makes a couple of small players that have all the same features as iriver (ogg included).
the iaudio players also function as usb mass storage drives right out of the box, for those who abhor stupid "media player" software and all their crappy DRM restrictions -- copying music (or any other file you want to carry) is literally plug-and-play, drag-n-drop.

Obviously you have never asked the question -- you would be suprised. The causes of asthma are multiple and their inter-relations are generally not very well understood.
Its called the "healthy smoker effect" and several prior studies have concluded that smoking has a protective effect against athsma. Still other studies have found conflicting results regarding the role of second hand smoke in asthma.
Subsequent reanalysis of the data revealed uncorrected biases which gives us the answer that we now believe to be correct.
Check out this quote from American Journal of Respiratory Care:
""" Smoking and adult asthma
A healthy smoker effect?...clip...
Unfortunately, the authors missed an opportunity to advance our understanding of cigarette smoking as a possible cause of adult asthma. This is because they examined the impact of current smoking at baseline interview on the risk of subsequent asthma, which may have biased their results. In Table 3 of their article, there is no statistical relationship between current smoking and asthma risk. In fact, the odds ratio is less than 1.0, which could erroneously suggest a protective effect of smoking.
These observations may be explained by a selection bias termed the "healthy smoker effect" (3). Because most people start smoking during adolescence, a substantial proportion will have stopped by young or middle adulthood. Basagaña and colleagues observed this phenomenon: at the baseline interview, 276 of the 1,264 ever smokers had quit. Many of those who quit smoking probably did so because they experienced respiratory symptoms, such as cough or wheezing. As a consequence, the pool of current smokers at baseline interview is probably enriched for persons who have experienced fewer smoking-related respiratory symptoms. In other words, the current smokers are "healthier" from the respiratory standpoint and are less likely to have, or develop, asthma. This selection process can bias the relationship between smoking and asthma, masking a true causal effect of smoking. In fact, this bias can even make smoking appear to reduce the risk of asthma, as recognized by previous investigators (4). """
