at first i was skeptical because of the reputation that preceded win xp and micro$oft in general, but . . . i've been running xp home oem on my new custom built machine for 8 months now, not a single bsod. a couple of boo-boos on my part caused me to have to use the system restore function. can't say enough good about system restore.
video capture and editing are a breeze, as is cd burning. i prefer to use third-party software in place of windows media player and movie maker. if i were a gamer i'd buy a stand-alone box, so that's not an issue for me. i follow this and other forums and tip sites and when i see a good performance tip i try it. this puppy runs a little better every time i use it.
is it perfect? no, no operating system will ever be. cdogg is right about running xp on older equipment. win xp forums are full of people with legacy hardware, software, driver, peripheral, etc. problems.
i couldn't be more thrilled that i've got a good clean installation of win xp. (fingers crossed) i have no experience with win 2k, but i've got a sneaking suspicion that m$ is going to stop supporting it before too long, just like they've done with win me.
cdogg -- positive enough? heh, heh. ;-)
