I'm just going to use RC1 64 bit ultimate edition which I already have installed as a dual boot option. Eventually they'll stop supporting it, but at the moment it still gets updates etc and doesn't look a whole lot different to the final version.
I don't have a key for Vista which would activate the final copy, nor the money to justify paying for ultimate. I don't know whether it would be worth paying for Home Premium or whether for the moment I should just use what is working quite well. Either way I will not make it my main OS just yet.
