The problem is the lack of windows. Windows should have windows, or they should call it Fullscreens so we know not to buy it.
Well, there's that.
And they made the start menu look like a teenage girl's myspace page.
And the new search never finds what I'm looking for.
And it pointlessly has "categories" or some shit.
And it takes 11 minutes to recognize that I've plugged in my mouse.
And file associations default to opening annoying Metro apps from desktop mode so I can't look at a photo while reading something else, without changing the associations.
And a zillion things like that.
And it has multiple screen support but it's worse than UltraMon, which I was using before.
And I can't upgrade my graphics drivers without bricking the whole system.
And even when I try to use the Metro crap, nothing works. Like I see an interesting news story in the News tile, click it, and that story is nowhere to be found.
And the two IE's don't seem to know about each other.
Oh, and since upgrading to 8, my computer can no longer wake from hibernation.
