i still use xp. im using right now. 7 is still a big box of tinker toys
to me, but will most definitely become my main OS soon enough.
xp had its run, time to hang it up, imo. my quess is that 7 will have at least the same life span of xp, maybe longer. it's not common for MS to "get it right" but the got a bulls-eye with 7 (and xp imo).... time will tell
