Seriously think about it for a second, 98 and ME aren't even in the same family of OSs as XP onwards. Secondly, Vista actually has a *lot* of good features, I'd argue that it is better than XP underneath (with SP) as would a lot of people that used Windows Server 2008 (since it's the same core and was their best server product by far).
And Windows 98 was basically just a bunch of service packs on from windows 95.
I'd argue that it's their new groundbreaking OSs that have let them down. They put something new and awesome in but waste so much time on it that they have to rush everything else through (all of the User Interface things which is why it feels so bad). Of course, the exception is ME, that was just terrible.
I didn't have to because I didn't waste my time or money updating....

I love Xbox Music already, though ads suck (even if they are expected and reasonably-spaced apart). Having the apps on your computer is pretty nice. I'm particularly fond of the Mail app, and having the weather right there is nice, even if I don't make use of the weather in real life (I'm wearing the same thing when it's 40 degrees in November as I do when it's 90 degrees in July). I've only tried a few games, but Jetpack Joyride is a neat one. Minesweeper is the same as ever (for the most part--they added different modes and challenges, EVEN DAILIES!!!), and I installed another game called Flow, but have not yet tried it. The browser is a LITTLE annoying (the non-desktop one), but not too much so.
I really only have one legitimate complaint, and it is that the browser does not alert you that multiple tabs will be closed. Since the tabs are not in your face (they're hidden above), I don't remember what I have open and Alt+F4 out of the browser with other stuff open, which is annoying but simply a habit to break myself of. That, and when you close every tab with Ctrl+W, closing the final tab opens a blank one, rather than closing the browser. I've had a few crashes of applications, but that isn't unexpected, and I'm sure we will see updates to fix that.
The UI isn't AT ALL hard to figure out, so I'll admit that those who have not REALLY tried it (going to Best Buy and whining for 45 seconds doesn't count) should probably just shut up. Like it has been said: there is an adjustment period, but after that, you arguably become MORE productive, and there is simply more to do. If I was to rate it, I'd say probably an 8.5, knocking off points for the occasional crashing and the browser. If/when the crashing gets fixed, I'd certainly give it a 9.
Note: I won't give anything a 10. I'd give Windows 7 a 9 as well, with this having the potential of a 9.5 (yes, meaning it would be a little better than Windows 7) as I adjust to it more.
