i mainly use the terminal... of course that is what i came up with for months all i had was access to a gepard server (aix unix ibm's proprietary unix) remotely for my class... no gui, just terminal so i'm used to it
also a good deal of packages (like glade) i tried to install graphically did not work worth a shit so i used the terminal and all libs and what-nots get installed
plus the shit is alot more powerful i can achieve so much more with one command... like moving multiple file from one dir to another... i could rant about this crap all day... my point is you should definitely learn the commands and how to use it... could really save your ass one day too lol
