First off I have to make it clear, no it's not going to be my default but I do have to be familiar with it. So I installed Windows 7 Ultimate on my Netbook to mess about with it for a while. It actually runs rather well on on this Atom single core CPU, of course the ION by Nvidia makes a huge difference. But I must say MS has finally released an OS that is usable, my first impressions are seriously this is the best release MS has done.
Anyway am I going to stick with it? No, I just need to somewhat literate with it due to my profession. Would I pay for it? Well if MS actually dropped the price of the OS significantly I would. I have a MSDN subscription through work so I get the OS's for free along with their developer tools and resources.
Well I'll be running it on my Netbook for a couple of weeks because as with MS every release they make pretty drastic changes that makes upgrades extremely painful
