I fancy buying one of these brand new for £100 without contract as they play games, MP3's and have an FM radio on them as well as being a phone.

Does anyone know of any serious downsides to this device ie are the games hard to get or do you have to pay a fortune for them. I've read a few web pages on them and it seems to have mixed reviews. The phone side of things is secondary, I just like the idea of an all in one device for such a cheap price.
