I think this is a great idea.
Giving the consumer more choice is a great idea.Companies shouldn't be able to say Joe Blogs is too stupid to use Linux. It also makes sense to get rid of a monopoly that allows one company to control a majority of the worlds computers. The more people who use Linux the more likely the hardware vendors will start supporting Linux by releasing drivers. That would also bring more developers to Linux and heopfully improve the various applicatiosn available. Big companies like Google, Mozilla and Dell are already starting to support Linux and that's really good for the future of computing. So yes, any support for a more competitive operating systems market is good for Linux and good for people who want to customise their computers.
