SlashGear : Why Haven’t We Heard About Linux’s Growing Market Share?

Desktops starting with Dell have begun being sold with Linux pre-installed, almost all of the new UMPC Eee-like notebooks that are selling in extremely large numbers these days are coming with Linux pre-installed, Everex is pushing Linux desktops through Wal-Mart, and lots of new computers are getting SLED certified or some other form of Linux certification. Add to that the increased popularity of all things Linux, the increasing ease of use of Linux as a desktop operating system and it has me wondering why there hasn’t been a spike in Linux’s market share?
