None, but that's not my point.
If they don't have better OS to offer, people will stick with XP until supports runs out in 2014 or slowly move to an alternative (this data won't be on Net Apps) and it's just my opinion.
MS don't make as much in OS as they did considering overheads. Compare the price of XP/Vista/W7 upgrades and you will get what I mean.
