I don't know what goes on behind the curtains of the Touch Arcade iOS app, but I've has one problem in using tt vs. browsing the site online...battery drain. I'm not joking when I say that using the official app drains about 1% of my battey every 2 minutes or so. When I browse the site on the web, including posting, searching, etc. I can go a good 10 minutes before I experience a comparable amount of battery drain. I understand that this might just be the nature of native apps vs. plain old web coding, but if there is any extraneous data transfer or Pre-cacheing going on, or whatever it might be, maybe you could look into it. Or not. Just bringing this issue up in case no one has reported a similar situation.
