If Linux keeps it's growth, by Christmas it will have "outsold", WIndows 8. Talk about embarassing for MS.

"A quick word about Linux on the desktop, too, because StatCounter has it growing from 1.34 per cent in April 2014 to 1.91 per cent this year. In January Linux's market share was 1.46 per cent. If that growth holds, Linux could be at three per cent by Christmas, by which time it will probably be ahead of Windows 8. ®"
