I guess everyone is different, but I prefer to install my software from CLI. With Mageia, fork of Mandriva/Mandrake, in a terminal all I type is "urpmi command name" and off she goes! It just seems to run and install faster then going into the menu's to find Synaptic or whatever GUI one use.
Since this is an RPM system, if a program is not in my repositories, I can google for it and download and then open up my file browser and double click the filename and it starts installing.
I haven't used Chromebook so I'm not sure how things work with it. I can't wait till I get one to try Linux!
