Windows 8 customer release just came out and I am loving it. I only wish I had a touch enabled PC to really get the sense of the whole operating system. I tried some slates at work and they are awesome. I cant wait until the RTM comes out.
I love the docking features, I love the mootness. I love the new ribbon of the normal windows we are used to. Although it is doing something weird, it seems to be syncing with something and I cant copy from one partition to another. I sill love it and will figure it out.
One thing to be carful with, when you are installing BACK UP EVERYTHING. When you install windows it, it formats your whole hard disk, including any and all partitions.
