I hate it because it takes about half an hour to install a freaking printer!!! :S

If I had known it was going to take that long I would have installed the printer another day (because I had something to do that day, and helping a friend install his printer took forever)

It is really annoying that when you are in the middle of installing something you dont really know how much time is left, all you see is a crappy bar repeating itself over and over and over again. The popups that keep on asking you if you selected to do a certain thing with the computer is really annoying. I know it can probably be configured so that it wont display the pop ups and other things to make it run faster, but you know what they say.... If its not broken... dont fix it. In my case windows xp does everything I need so why would I want to go ahead and try something new if there is no need for it.

I hate because it use a high-end hardware such as RAM.
my PC is an old one with low RAM 256MB

btw2 the look of vista is good., i like it

You have your answer already - it does not work
with older games (and other software).

If things work, the audio doesn't play.

If audio plays, other error messages appear.

Lots more but I can't remember what else cos I was
lucky to poll, and then read reviews of other sites
where members gave honest reviews why Vista isn't
working as well as Microsoft touted.

That made me stick with XP. I mean....strangers
have no reasons to lie to me, when they don't know
me. I just love the spirit of sharing info!

If Vista works for you, congrats! May be your pc is something
and you should share its specs.

I can't say it's a good or a bad Operating system...
The Problems are:

As others said, older programs do not work well or it does not really work with Windows Vista. I have some programs/Good Programs that I like which is not compatible with Windows Vista and I wonder why?

Also, the system requirements gives many people a headache [Including me ] I've upgraded my Computer two times and upgrading to Windows Vista? [Well, I should think of upgrading or to stay with Windows XP Professional]

I'm hoping that next time with the upcoming Operating System, it would be greater, we all expect for the good. And I also hope that Microsoft is listening to our complaints, comments and suggestions for the sake of everyone...
