Ok, thinking of giving XP another try, but there were a couple of things I wasn't too sure about: I'm pretty sure that XP uses NTFS, but are you still able to share files with a FAT32 machine? Some of the other machines on my network are running 98, and I'd still like to be able to share files with them. What sort of compatability issues have people run into with software. I think that most recent games should be fine, but I'm thinking about stuff that's either a couple years old (like UT, Quake 3 etc) or smaller utilities (Cute FTP, CDRWIN, CloneCD etc). Rather not have to find replacements for all of these. What sort of decrease in performance can I expect from the OS-I know that it's got a LOT more overhead than 98 (just from system requirements on games), and just a little worried that some of the benefits might get lost. I'm running a P4 1.6 at 2.13 GHz with 512 Mb, so I'm not all that worried, but I want to get the best performance possible.
