I don't like the whole tiles thing that MS has been trying to push lately. Its okay on the Xbox, but as for a computer/phone/tablet OS I just don't like it at all.
I installed Chrome and it worked until I closed, then it never opened again. Had to restart the computer just to open Chrome like 5 times. Ended up having to edit the Registry just to make Chrome work.
Comes with a lot of bloatware, so I wanted to uninstall some. Every time that I uninstalled a program it closes every window that I had open.
I have two monitors(laptop screen and one more) and every time the computer goes to sleep it defaults back to duplicating the screen on both instead of expanding, and it changes the screen res to really low.
The Desktop app is just a really watered down shitty version of the Win7 desktop, minus the start menu, which is a major pain in the ass.
And the last of my complaints so far is that the setup is very counter intuitive to me. Things that I needed were in strange places or accessed in a weird way, I don't like looking up how to do simple shit like uninstall some programs

/rant accepted. Glad to hear this before I went all W8 crazy. I still might try it, but I am worried that Windows 8 for the holiday is going to be a great disappointment.
