Me too. My Vista machine has been running 24/7 for almost two years, and
never a single freeze or BSOD. I get the odd application crash (Word 2007
mostly), but you can't blame the OS for that.
I think the user interface is far from perfect, but much nicer than XP's (it
treats me like an adult, not a child).
It doesn't seem noticeably slower than XP (although I accept that benchmarks
will show a difference), apart from copying files across the network using
Explorer, which is still a bit slower. However, I use Directory Opus, so I
don't care.
UAC prompts are extremely rare now, and only occur when I'm about to do
something at the system level. In that case, I'm glad that Vista says (in
effect) "This may have security implications, are you sure?". It's only the
same as Linux and OSX in that respect.
My machine is used every day, mostly quite hard, doing a vast range of
different tasks.
Personally I'm pleased with Vista and like it.
The most vociferous naysayers are Linux users, or XP users who have problems
coping with change, and there is an undeniable tinge of desperation in their
tone. The kind of frantic bad-mouthing they indulge in sounds very
defensive to me. The fact is, they feel threatened by Vista.
