Although cell phones now include megapixel cameras and MP3 players, I would not recommend getting rid of your gadgets completely. Even a phone such as the Sony Ericsson K750i, which has a great camera and music player, won't give you the quality you'd expect from a stand-alone camera and an MP3 player. The K750i has only 64MB of song memory (a far cry from the 20GB iPod!), and the interface and features just aren't comparable. Also, the camera is nothing you'd want to use for a family portrait or take on vacation.

That said, if you're looking for a convergence device to use while on the go during the day, the Sony Ericsson K750i is a great choice. You should also check out the Sony Ericsson W800i and the Nokia N90.
