I don't know how it's going in other countries, but, here in Brazil, who bought a PC/note with Vista can receive
for free a XP Pro license.
I bought 2 PCs and got 2 keys for Windows XP.
BTW, my brother got 2 XP and 3 Vista keys on MSDNAA.
I'm about to get mine. The results are out on Feb 7th [good luck to me
]
I guess I'll make a collection of Windows' Keys.
