I think everything is very, very user-friendly, actually.
At first, I thought the separation into Metro and the standard Desktop was ridiculous, just like having to move your mouse all the way to a corner in order to do certain things. However, after getting used to it (which took only two days), I can work waay faster than before, using those corner commands. As for Metro, I don't really mind it, but I think it is really weird how Metro Apps and Desktop programs are treated as two completely dfferent things. For example, because the Desktop is actually a Metro "App", using the corner command for switching between windows, you can choose all your current Metro Apps separately, but can only choose your Desktop as a whole, no matter hom many Desktop programs you're running.
But I really like how it warns you several days ahead of when it has to restart because of updates. The level of customization you get for the Metro menu is also great: just being able to slide those squares around and change background patterns and colours is very satisfying!
So in short, I really do like it!
