Today the new Zune platform is released by Microsoft. Called the Zune HD it looks absolutely wonderful. It has solid state storage, an OLED display and a multi-touch user interface.
And, (and this is the wonderful news) it supports XNA. A set of XNA 3.1 Extensions has also been released which you can use to take your games and run them on this fantastic platform. And the extensions even provide access to the accelerometer and the multi-touch input.
If Microsoft get around to putting a phone in there too they will have their first proper iPhone beater.
The only snag is that for now it is a US only release, but with a bit of luck it will make it to us eventually.
