The thing I don't agree with is that it's a Kindle-killer. The new iPad comes with a comprehensive, really super slick bookstore and reading interface. It's loads prettier than the Kindle.
For starters, the display is not eInk, so it's going to be a bigger strain on the eyes. But more importantly, it's a friggin' computer. Maybe most people have better willpower than me, but just knowing that I can check my email, jump on the web, load the Facebook app, etc, is going to keep me in a constant state of distraction.
What I love about the Kindle is its simplicity. I dunno. Maybe the iPad will kill of the Kindle. But I'll at least be sad about it.
