If things work well for you, I'd stand pat.
But for me, Windows 98 limitations of 4GB file sizes, resources and 64 kilobyte resource pools have me running Windows 2000 and XP for the machines I have for video editing and more.
I currently am running an up-to-date version of 98SE on my about 4 month old P4 2.4Gh, 800 FSB, 512K pc3200, etc. For Xmas I received a full install version (not upgrade version) of XP Home.
Should I wipe out the system and go for the full install of XP, or keep on running 98SE.
What will I loose/gain by staying/going with each operating system, and what would you recommend??
