I recently read with great interest Walt Mossberg’s review of the latest Ubuntu Linux, described as “relatively slick,” but still not ready for non-technical users. I have a couple of differing perspectives. The first is that Ubuntu is ultra slick. It’s free. It’s open source. It’s growing. It’s Linux and it works (usually). My second point is that yes, Ubuntu and increasingly Linux distributions in general are getting easier to use, but they are still difficult enough to change your perspective on computer use.
