Vista on my lappy is stable as a rock ... admittedly, the first thing I did was uninstall all the crap that dell bundles with it.
I bet you left that god awful Roxio Easy CD suite on there, didn't ya
With the packet writing sofware .. about as stable as a one legged nunriding a unicycle on a tightrope carrying a 50KG bag of bricks in one hand, and a cement trowel in the other.!
First thing to be uninstalled on mine
But DAMN! Vista is slow ... try copying some things across a network on gigabit ... or even between two [sata] HD's (on a desktop PC) and you'll see what I mean.
Vista spends 10minutes thinking about how long it will take to copy ..... it then takes 8 minutes to copy it, reporting progress relatively reliably.
WinXP spend 8 minutes copying it, and randomly tells you it's gonna finish in 15min, 20min, 3min, 10min, 17min, 6min, 4min, 8min, 40sec, 3min, 20sec's, 10 sec's, 30sec's, 5secs. Done!
I'd rather XP's way of doing things
