The number of "improvements" are immediately invalidated once a person is confronted with the hostile UI.
lol Hostile UI? The only significant changes to the UI on the desktop are the loss of transparency on window borders and the addition of the ribbon (which can be disabled, though I forget where I got the program to do that). Honestly, once I got my frequently used apps pinned to the taskbar I can hardly tell the difference from 7. I even got my sidebar gadgets back thanks to somebody on another site who ripped the components from the release preview and put together a batch installer. If you happen to have a ******** of apps you use frequently, Bins has been updated to work with 8 so you can group your shortcuts. If you can't live without the start menu there are a ton of 3rd party programs that will add it back for you (I personally prefer Start8). Yeah, I'll agree that you shouldn't have to install another program to restore or enhance functionality so it works as you would expect it should (like previous versions of Windows), but I really don't understand people having this extreme a reaction to a change of the application launcher.
@OP: I'm sorry Windows 8 didn't work out for you. 7 is a great OS, too, so it's not going to hurt you considerably to stay with it. There were a few irritating bugs that I won't miss, but essentially 8 is to 7 what 7 was to Vista: a service pack. I'm glad I only paid $15 for it, because I probably wouldn't pay $99+. But that doesn't mean I regret it, at all; I'm thrilled that MS was practically giving it away at launch. It probably cut down on a lot of piracy, too.
