Walt Mossberg lays the smack down on Ubuntu.
I agree that Linux isn’t right for a lot of people, but some of his points are a bit off base. For instance his complaint about having to download codecs just to play an MP3 or a video, he states that these codecs are included in Windows and OS X, however, there are quite a few codecs for both operating systems that you have to manually download and install in order to play content encoded in that format. DivX and Xvid come to mind right off the bat, neither of those formats is supported natively in either Windows or OS X. Sure MP3 support is something you’d expect out of the box, but it’s not the end of the world.
