I pre-ordered 2 copies, with the UK offer. Still not received it though, due to said postal strike.
Am reserving some judgment till it's installed on my machine, however quite liked it running in a virtual machine. Have done many hours of research into what's new and what's changed. Apparently MS have a 140 page document detailing "what has changed".
Can't be any worse than Vista, surely?
In many ways, I think we can be thankful of Vista, as it gave MS a wake up call. I don't think Windows 7 is the future, but it's a step further in the right direction.
