Is the bump in Linux attributable to Chromebooks/Chrome OS? There's this thread from a year ago speculating about NetMarketShare's methodology with regards to Chrome OS, but nothing was confirmed: http://www.omgchrome.com/chromebooks-fuelling-rise-linux-os-...
If true, it's incredible that this seems to be biting directly into Apple's marketshare: the Generation Z "I'm a teenager/college student who just wants to use Facebook and do all my homework" demographic now has an alternative to the millennial's "I need a MacBook to be cool and work effectively." Tremendous ramifications for those of us who still make desktop software, especially in the professional multimedia space.
