I got another PDA. A friend of mine from Wednesday night poker sells PDAs for Microsoft, and he had a bunch of older demo models just laying around, so he perma-loaned me an HP iPaq 5455. On Friday I went out and picked up a 1 gig SD card, then spent the rest of the weekend setting things up. I've scoured FreewarePPC and installed just about everything I need — emulators (NES, SNES, and Gameboy) and their associated ROMs, an MP3 player, and (of course) and eBook reader. Anyway, I've been out of the PocketPC game for over a year, so I'm open to suggestions. Are there any killer apps I should be using?
