But you do have to learn how to use a desktop. You even spent sometime learning how to use a mouse. I use xfce on my main machine and unity on the oops I need skype machine
and I hate the switch, but that's because I have not invested time to use it well - and chances Are I probably won't, just like I won't learn the annoying parts of OSX
desktops are a tool like any other - the mentality that they should be intuitive or easy leads down the path of eye candy as opposed to functionlity.
when you learn to drive a car.... you can drive almost all cars... the biggest difference is with the manual o automatic gears....
when you learn to use a computer you should be able to use many of them whithout having to learn anything.
A car does one job. A computer does many jobs. Learning to do each job a little differently, adds up to a lot of learning. I don't know what "you should" has to do with it - I'm just pointing out that for all desktops that currently exist, you have to learn how to use it.
