I've got 8 and am really missing my Vista. I dislike the side bars that slide out left and right if you move the mouse in that direction to, say, scroll down and which don't want to appear when you want them to. If I click into a photo or a download there doesn't seem to be a close screen to click on and I have to get the side bar to come out to take me back to the icons and then back into Firefox.

That's just for starters. I can only open Word by going into documents, opening something up and then it takes me into Word and I can open up a new document.

While it is faster starting up closing down is a pain in the arse. I have to go onto the icon screen and log off and then wait for a while until the sign on screen comes up and I can then click in the lower right hand corner and, finally, click close down.

Faster machine but the applications are more complicated, which slows everything down.
