Since we're being pedantic: I am a Linux user. I was using virtual desktops on SunOS before I ever used Linux. Therefore, Moblin zones are just the virtual desktops that I (Linux user) have been using since before Linux existed. 
Ultimately, I think the sentence is simply the grumpy editor being grumpy ... and dating himself.
 In reality, my virtual desktop experience probably began in 1993, up to 2 years after Linux was unleashed onto the world; anachronisms aside, I think the point remains.
