Phone, iPod, GB Advance, WiFi and Camera included (Score 1)

Here's my killer app: A handheld w/ a fast processor, color screen and the following: -phone -WiFi -Hard Drive -Digital Camera Oh, and a GBA emulator available for it. Throw in a hard, waterproof case that holds my credit cards and licence, too and I don't need anything else. Grab this on my way out the door and that's all. There's a iPaq that does quite a few of these things, but only works on T-Mobile. As far as I know, there's no WinCE GBA emu, either. I'm sure it'll be around in a few years. With all those features, perhaps if I start saving now I can afford it then.
