I use OSX at work, and I haven't *HAD* to open a shell for anything when it comes to day to day use. There are some things I find quicker to fix / install from the shell, but that is my choice -- I am not forced to. I have found the same to be true with Linux Mint.
If you look at my post history, up until recently I was a die-hard Windows fan when it came to my desktop OS. Even OSX is missing little things that Windows 7 has when it comes to window management. For example, Aero peek on the superbar. I didn't realize just how much I used that until I was forced to use OSX at work. Also, clicking on an running app to minimize it. I could go on, but an OSX vs Windows vs Linux debate is not what this is about. I still love Windows 7, and if MS ever gets their head out of their ass and releases a decent OS again, I will be glad to use it if I have to. Again though, the point of my post was to let people know that if they hadn't tried Linux as a desktop OS -- maybe they should. I am a convert now, and unless The Linux Mint team decides to go full retard (like MS has), I'll stick with it.
