We already had the year of the Linux desktop
For me, it's been the 'year' of the Linux desktop since 1995. That's when I started using Linux on a regular basis. My first distribution was Slackware. Slackware is still around, and it's still a fine Linux for people like me who came to Linux from Unix.
Let's get real though. There have never been that many people to whom the arguments over whether the Bourne, C, Korn, or Bash shells were the best desktops really mattered. I still maintain, however, that Korn is the best since you can do serious programming in it while maintaining backwards compatibility. OK, so that kind of thing still matters to me and to other die-hard Linux/Unix users, but no one else really cares.
