I bought Vista H.P. around 8 months ago.
First impressions were:
-General slugishness around windows (expanding, minimising etc)
-Terribly slow transfer speeds (hdd - hdd, network transfers etc)
-Lots of RAM usage compared with XP.
-Crashed quite a bit.
-Performance in new games was pretty bad (esp CoH)
-
-Slugishness
You have to be kidding? Have you turned off "Animate windows on expanding"?
That doesn't even look sluggish, it's very smooth and with it turned off it's instant.
- Transfer speeds
Well yeah, this was an issue but is now fixed
- Lots of RAM
Well I'm on 64 bit and the difference isn't huge. It's also down to superfetch which works really well.
- Crashed quite a bit
Check your PC, I haven't had a single BSOD (touch wood)
- Performance
On the whole it's equal to XP and video drivers are pretty good now.
What you should have done was install Vista and all of the updates (minus SP1) and tried it then and apart from the HD transfer you will still be happy.
