not really, i was dubious about moving to win7, but i was proved extremely wrong, like many ppl, and think its totally great
im all for moving fwd, but only if its really something that i need and will improve my experience, so far win8 doesnt seem to do that, but time will tell
i certainly wont be using it till i get a new machine, and that wont be a for a few years yet (my last one did me well for 7 years)
