Google is registering 1,000,000 Linux machines a day. Small desktops, granted. But (IMHO) the Year of the Desktop was really about the year of Consumer Linux, which snuck up on everyone upwards, rather than flowing down in machine size.

I know you're joking (and I doubt Linux on the desktop will ever be a thing) but it would be hilarious if Microsoft were the one to propel the old PC assemblers into making a Linux push.
