Current iTouch/PDA alternatives

[Youn]

Need some help. I'm looking for a handheld devices with the following features:

• touchscreen
• pocket size
• wifi internet browser (javascript, flash support not required)
• mp3 playback
• decent battery life (at least a few hours)

I will primarily be using it for a remote control for my av system (via local network web server) I don't care so much about screen or sound quality, video, camera, speed, or even disk space. It would be nice, however, to have something like SD card support for file transfers.

I know I can get a used itouch for less then 100 bucks, I may end up doing just that, but I'm trying to widen my search.

thanks
