I love command lines, and I use them every day. Most of my work is on a command line... in a term window in X. The Linux virtual terminal system was a great advantage. The ability to run multiple terminal windows on-screen at the same time, with a clipboard! that was an amazing achievement. Virtual desktops? Great.
All of these things are advantages, and you don't need to stop using the good stuff that works in order to use the new stuff that works. Today I click on one of my sidebar icons to summon the terminal windows in which I do most of my work. I have enough RAM that I can keep heavy graphical browsers open -- FF and Chrome -- with hundreds of tabs open.
I'm happy to be able to use everything. I'm happy to have choices.
