I don't get the 'screen is too small' argument for existing iphone / ipod / treo /etc reading. I completely agree with you - when you get into the material you're reading, the format just 'goes away'. Why buy a big clunky device when you're existing one works fine?

Seems pretty desperate to insist on citation to me - I note it suggests being the 'primary reference' in articles and essays! Well, no - if my students cite W|A as their primary reference there's going to be some low marks flying around. Similar paranoia surrounds Mathematica - download their 'home' version and you're apparently forbidden to publish anything 'discovered' with it. This is apparently a privilege only afforded to purchasers of the 'full' version. Fine. I'll keep using my existing software - imagine being stymied by having your breakthrough at home only to be sued by Wolfram for having your idea on your own time instead of, oh... your own time. Wolfram needs to take himself and his products less seriously.
