I champion the fact that the iPad 2 maintains the 1024x768 resolution.

While newer tablets are pushing 1280x800, it seemingly has a large effect on interactive framerates which hurt the user experience. Based on what I've seen (and what I know of these two resolutions), the gains in resolution are not worth the compromise in performance (IMO, of course YMMV).

I suppose I would have to see two devices running side by side, but I would rather have a 1024 running at 60fps than a 1280 running at 30 (yes, I know these numbers aren't real, I'm just trying to communicate my preferences).
