Hello Kitty,
You've been using it for a day, and you already consider it being crappier than Windows Vista? Are you insane? You as a developer yourself should know that 1 day is NOT enough to test out a OS completely. I've been using Ubuntu 9.04 "Jaunty Jackolope" for a month, and I know for sure that I have not explored it 100%. Ha-Ha, I doubt I've even explored Ubuntu 10% even.
Let's start to show WHY you didn't explore the OS properly,
1) in PART-2 you whined about how you had all this rubbish that you wouldn't need like the games folder, well, good news mate, you can toggle, and in fact, add stuff onto that. How? Click on your taskbar and go to properties, go to start menu, then click on customize.
2) in PART-2, you also whined about that picture, are you blind? Them pictures were integrated into XP long time ago, and they're just there for when you've got multiple users, so that the less computer literate ones can identify their user account easily by a picture that can be remembered easily.
3)in PART-3, you complained about the themes, well, that's the thing, most of the power users of Windows often use with Windows 98 theme, however some think that it may be nice to have a custom theme like that of the Gaia series. Different themes/colors have been around for god knows how long..
4) in PART-3, you complained how you background didn't change, well maybe YOU cocked something up! I've been using Windows 7 for ages, I've cocked it all up to a high degree that I've even modified explore.exe(Just to change the taskbar icon. ^_^), and I've never came across this background problem that you have, in fact, wait, stop? I recall this being a problem in WINDOWS-XP, it's called a cache, you have to log-off then re-log on, that'll clear your cache, not only the OS' cache, but your web cache too. In fact, I'll even show you a video of me changing my background in Windows 7 perfectly, if you ask.
You're trying to believe that Windows 7 is more terrible than Vista. You're obsessed with degrading new equipment than that of what was old and is still terrible. I really don't believe you're in such a state to call the shots on whether the OS is bad or not. Just because you ran into a few problems doesn't mean that there's another way around them.
Also my guess is that you used Ubuntu--- that, or ArchLinux.
