Microsoft had a few good ideas for windows 8, but still needs a lot of improvement...
For example, I like the fact that you can put a win8app on the left/right side of your screen. Quite useable when chatting or listening to music. But they'll have to improve it...
Also, for almost all apps that use internet you have to have a microsoft account...
And I have lots off compatibily issues.
Also, the menu's that open when hovering the corner of the screens could get quite useful with a little improvement. esp. for fast access to some programs/options...
And the multi-screen support is better than in win7...
