98se is very good, however, the ram not being dumped bothered me....ME is a horribly rushed piece of shit and i highly advise you to play frisbee with its install disc.....2000 is the worst supported by far......XP will run with most things, unless they are specific DOS mode games, and even then it will run most of them. for some reason, my XP cannot run warcraft 2 or NFS 3. of course, it didnt really bother me, just something i noticed
for copying, the only issue is stability, and xp/2000 win hands down there
