Don't do it. Microsoft somehow managed to rip off the most annoying features of Mac OS and break half of the features in XP and Vista. Instead of having a quick bar (shortcuts), a task bar (running programs), and a system tray (background programs), it now has the dock menu. Shortcuts and running programs look the same. You'll minimize something, forget that it's minimized, and wonder why the computer is using 3gb of ram to do nothing. Oh it's because I have 10 firefox windows open and didn't know it.
Here's your familiar Windows XP/Vista desktop. Nice, clean, organized.

Here's Windows 7 running the same number of programs. It looks like shit. Notice how MSN messenger no longer sits in the system tray; it takes up
2 spots on the dock menu. Shortcuts (the ones not highlighted) don't stay on the left side anymore, they just go wherever the hell they want. It makes the system harder to use because the shortcuts are never in the same position twice.

Driver support is horrible. My HP Laserjet 1012 printer works great in Windows XP, good enough in Vista, and it flat out doesn't work in Windows 7. My printer/scanner (HP 1500?) works great in XP with proper drivers, works as a plug n play device in Vista, but is not detected by Windows 7 as a scanner.
I also put a video on youtube to vent my frustration with Windows 7's complete inability to work with network locations. Unless you know the
exact folder path and can type it in the address bar, you're fucked. It can connect to network locations, but only if they are typed in.

This is Windows ME all over again.
