I do like Windows 8. Even more than 7. The ribbons are actually useful in the explorer. I like the new design. These flat colors rather than gradients. And finally the new start menu aka tiles. I prefer them over the classic start menu and it still allows my win7-way to start programs (win key -> start to type the application name -> hit [Enter]).
I do not like the app store. I don't want a Microsoft account, especially not a hotmail account. That sucks. Even though I like Windows RT and WinJS so far.
