Flip! iLove my iPod Touch. It is so slim - smaller than the iPhone - and has so much power. I've hacked mine (well, of course!) using the wonderful Jailbreak and some other geeky stuff so now it has a host of powerful applications - screensful of little icons in fact - and is well on the way to being a fully functioning little computer on its own.
Mine is currently having much fun running as a web server too (good old Apache!!) but it is the very sensitive and subtle motion detection that is so seductive. And using Remote Buddy I can even monitor the live video camera on my MacBook remotely over a wireless link - from anywhere! How cool is that! Very.
Listen, just go out and buy one. I've bought eleven so far (well, children, partners, etc etc) and they are all fab!!
