Just notice looking at the netbook topseller list on my blog: none of the top 10 netbooks got Linux, they are all shipped with Windows XP.
Did Linux loose a chance to get to the people? High return rates burned fingers of Asus, MSI and Co. Mainstream netbooks in the next 18-24 months will still be shipped with XP and the new Windows 7.
In any case I do think that Linux still got a chance: a few OEMs (e.g. Dell) instist shipping netbooks with Linux and big names (e.g. Intel) are spending big money on Linux for netbooks and portable devices (mobile phones).
Help is also coming from Intel's competition: Linux is the only reasonable netbook operating system for ARM based netbooks and the recent announcement of Flash 10.1 supporting ARM is a great news: finally ARM based netbooks gotta a chance to offer decent internet browsing experience.
My bottom line: the situation can only improve!
