Cool Product – OQO

My flatmate just go an OQO and he hasn’t stopped raving about it.

A small PDA type device, however it runs a full version of Windows XP, has a full keyboard, mouse and keypad, a screen of 800 x 480 and build-in Wi-Fi and wireless broadband that can be connected to a telephone provider. Apparently with Skype installed you could then use it as a phone. He just tested it as we were talking to see if it had a built-in mic. I must admit even I’m impressed. Something I’ll need to play with a little more. Doesn’t beat my iPhone however for the cool alpha geek, in your pocket sized being able to show my photos & view the web device.
