Ive had the release the candidate 2 since it was released this friday just gone, and might i say it's a very impressive operating system it defintley looks like a near finished product. The user interface is a great improvement on the XP interface, i think the greatest improvments are the stablility and speed of Vista and the backwards compatiblity with x32 applications as well as x64. I managed to install all my games without any compatiblity issues and they all played fine actually some played better than on XP. The new TCP/IP stack includes full support for IPv6 alongside IPv4 handy if your ISP supports it....
