Here is a story over on yahoo about the emerging Linux PC. I'm a big fan of Linux and Open Source software in general. However Linux on the average consumer's(that includes business users) desktop is just not going to happen other than in the niche its already in. The only vendor that has made any dent (small dent) in Microsoft's PC OS realm is Apple. You can make arguments all day long about the differences in the technology but it makes little to no difference.
It would be like your favorite local brew pub going against Anheuser-Busch. Of course I will look back on this in 10 years to see if I just completely missed the boat but somehow I don't think so.
