presently I have Win ME and so far has been ok but has had its up/downs..matter of fact I have to leave PC on, Monitor off in fear of coming up with HD errors...anyhoo, have been pondering to make the switch to XP but have been hearing some real HORROR stories about problems with it, especially with SP2; even got word from HP software specialists that if I do make the switch, DON'T GET SP2! I guess eventually i'll be forced to get it but for now am holding back...any feedback would be greatly appreciated.
