Proper market regulation

Do we have a good current picture of what the OS market share is in the netbook space? Dell's last report that I saw was that ~1/3 of their netbook units were shipping with Ubuntu. And credit where credit is due, Canonical seems to have built a solid business relationship with Dell.

But I haven't seen anything market wide for the last two quarters I don't think. Are there any other major OEMs still shipping new linux netbooks other than Dell. Acer,Asus,toshibia,hp...any of them? Is linux pre-installs of +10% of netbook sales in the last quarter for anyone but Dell (and niche OEMs like zareason?) And I don't just mean US markets. Are the demographics in linux netbook sales in other locations vastly different?
