The process to get Windows 8 working (with graphics correctly setup etc.) is a little bit of a pain but nothing all that difficult. Especially if you follow the steps (usual rules, I made mistakes to save others the hassle )
The resulting install of Windows 8 running at 1024*600 is VERY usable , much to my surprise. Metro is actually quite nice on the tablet form factor.
The touchscreen is a little unresponsive round the edges but I suspect that is my device as it has never been very good.
