I don't know about the others, and what problems they are having, but until now, and I consider myself lucky, I've had absolutely NO problems with leopard. I've no problems with the Time Machine 10GB problem. No installation problem. No Alex problem that Aayush has had. I'm saying all of this truthfully and honestly. No hangups.
And as for the huge amount of criticism received for the new dock and menubar, I love both of them! Honestly!
I also think that many others are as lucky as me with no problems as it's usually the one's who have a problem that make a noise about it. It's the same case with the 10.4.10 update. I stayed away from that update cause there were problems of kernel panics and such associated with that update. But when I did install it there was *almost* no problems (audio popping issue sometimes)

Woah! Now that I removed Vista and put XP on my PC, I can finally share internet with my Mac. I thought, why not use Mail for a change. Little did I know, I just had to enter my Gmail ID and password and the whole thing was taken care of! Nice...
And the dashboard web-clips thing is also pretty awesome. (only a little buggy in that I can't access the options for web clips...the 'i' isn't showing anywhere)
@leopard boys: are your screenshots using the command+shift+4 coming a little blurry? The com+sh+3 screenshots look sharp, but the other ones are a little blurry...
