W3Schools has the stats up for June. That other OS is down to 85% share. Android/Linux has had 100% growth in the last six months, 300% per annum, while iPhone has been static, iPad has had 50% growth. GNU/Linux’s share rose 8% in the last year while that other OS’s share dropped 3%.
It looks like “7” might finally catch XP after two years of retail sales. Since the world is getting off the Wintel treadmill, this may be the last time any release of that other OS reaches 50% share. Between switching to thin clients, ARM and longer refresh cycles, the world will soon find that other OS is not “the standard” desktop.
