If you have sufficient hardware for XP, there should be no reason you need more just for an OS

True. I'm shocked that it wants me to upgrade my old MS DOS 3.3 machine, 256K of RAM and that 10GB HD is more than enough for anything! ;)

Seriously, you can't expect a new OS to use the same hardware configuration of an 8 year old OS, hardware and software minimum requirements move forward.

FWIW, I tried the upgrade advisor on my Vista machine and it was completely happy with everything.
