In today's news:
Wal-Mart stops selling Linux PC's in their stores. They sold the PC's for $199. Wal-Mart will still sell them through their website.
Not sure if this is because of Linux or the quality or marketing of the $199 PC. But overall not surprising. I'm not sure that the average customer would be geek enough to run Linux, or if Linux is mainstream enough for the general population. If I was going to run Linux (which I tried and disliked) I would download it or buy the CD and install it myself.
