Have you tried setting Windows 8.1 to head directly to desktop instead of Start screen?
It's a bit hidden, but still fairly easy: Right-click task bar -> Properties -> Navigation Tab -> Start Screen section.
I've been on 8.1 professionally (for my job) since august (preview initially, then RC, and then RTM). Didn't even notice it came out officially on Thursday. The argument for staying on Windows 7 is generally "it works fine for me, why upgrade?" Which was also said of Windows XP when Vista and 7 came out. Vista was a dog, but 7 was pretty good. 8 is even better. It's faster in damn near every way, and 8.1's keyboard/program search is even better than 8's, which was pretty damn good. Combining the 3 separate search categories (Programs, Settings, and Files) into a single unified search is so far my favorite feature.
