Anyone tried Windows 7 Beta yet? I was just curious to see if anyone had tried it? I read on engadget that its been out on public release for a bit so went to my favourite torrent site and found it there. Seems to have some great reviews and be a significant improvement on vista (not that it's much of a challenge :? ). I particularly like the fact they have integrated CUDA into the performance enhancement of the OS. sooo.... opinions/experiences?
