I went to HP's web site and checked a netbook, laptop, and two models of desktop. The only operating system options offered were flavors of Windows. I know where to find Linux systems on Dell, but that's only because I spend some time digging for them. Vendors may offer them, but they're apparently not bragging about it.

So with Linux on 33% of netbooks, and netbooks 20% of the new sales market, Linux netbooks account for 6% of new sales. Not 6% of the total number of client systems, just new sales. Hardly the 'swarming' pogson describes.

As to the amount of time to Google, I'm not going to do someone else's research for them.
