I recently switched from Win98 to XP. Boy what a difference. I had constant rendering lockups in 98. Now EVERYTHING runs at least 4 times faster. For some reason my cable modem speed increased by a factor of 4 to 10. I was able to get patches for my periphs (printer and scanner) for free. Poser hasn't locked up yet. Some games won't work. Ultima IX claims that XP is mainly for businesses?. All in all it's the best investiment I've made in a long time.
