Would be great if it worked
The machine seems generally well built but my one had a faulty disc drive. A quick google search found that I am not the only one. Many customers have ended up with machines that will not recognise discs.
The new dashboard is a pain to navigate. Microsoft seem to be forcing users to use the connect by making it nearly impossible to find many features quickly using the pad and there seems to be no way of actually stopping an installed game from running once it's been started.
For the money you may be better off upgrading your pc instead.
