Adding to the bottom with the view pegged to the bottom of the screen is the best and more natural way to do it. You still see everything new, and you don't have to see it appear backwards. Hijacking keyboard input completely also really sucks. I'm surprised a web page can even do that. IMO, huge security hole.

Surprisingly they didn't kill the old iPod Touch. Kind of tacky decision IMO, that thing is already 2 years old. Like every iPhone event since the first, Apple has mostly impressed with the hardware, but the software advancement for OS/built-in apps has been a real let-down overall.
