According to NetMarketShare..com, Windows XP has finally fallen below the 50% mark in market share. Windows 7 is gaining and is at nearly 28%. Vista is well below that at just above 9%, and Mac OSX 10.6 is at ~4%. One thing I do notice is that the iPhone (iOS) is gaining and may pass the Mac OSX in market share. Apple knows it’s cash cow, and it’s not the Mac.
