I imagine some of you have already seen this as they've been talking about it for a while, but if you haven't heard of OnLive check it out; it's pretty amazing.
It works with PC, Mac, IPOD's, IPAD's and straight from your HDTV's with the OnLive MicroConsole TV Adapter. It also works with your existing PC game pads and Xbox360 controllers and Mac equivalent.
With this you can game at home and then carry on from anywhere else when you're out and about at work or whatever, with a the installation of a small browser plugin.
Its got some amazing features, that neither Xbox or Playstation have. I like the way you can log in and watch anyone else game in real time (live) all over the world, regardless if you even own the game. (You can disable that though)
Anyway, check out the links and see what you think, it might be worth signing up to reserve your screen name you normally use as the service is still early days.
