Apple is making the wait for iPad interesting, at least. You can spend the next 24 hours shopping for iPad apps. Most importantly, of course, is iBooks, which has just gone live in the App store. Get it now, while there’s not “line.”
Presumably, in addition to building even more buzz, Apple is trying to avoid a repeat of the fiasco at the iPhone 3G launch, when iTunes was so clogged with new users trying to download the same things that it ran like sludge for days.
