We bought ME for two of our comps here at home when it first came out. On one, it ran perfect, the other, bug city! Blue screen of death everytime we turned around..the two machines were virtual identical, hardware and software..maintained the same, etc. Upgraded both to XP, no more problems....I've had XP for about 3 months before release, NOT ONE BLUE SCREEN!! That's says a LOT about an OS!
