Well I just installed Windows 8 in a partition in my main computer
It took about 10 minutes to complete and it only used 10gb of space on my hardrive. Thats awesome
So far its working great,it boots faster than windows 7, thats great for my crappy 3 year old laptop.
I like the new interface but there are things that need a lot of work. Lets hope that all will be better for the beta
I'm liking it so far
