Hehe... Didn't expect quite so much response to this.
So basically when I first started running Linux very recently, I tried out Mint 7 Main (Gnome) before anything else. Mint was my first ever Linux distro, and it COMPLETELY eased me in.
I loved the look and feel of the GUI, and while not quite understanding the terminal, I'm slowly picking up some basics and love the power behind it.
I went to try Kubuntu because I know Mint is originally derived from Ubuntu, and Kubuntu being the K "spin off" I figured I'd give it a shot. I enjoyed it and that's what led me to try out Mint 7 KDE CE.
Also loved it.
I haven't used ANY DE extensively enough to know what I prefer or what would suit my feel better at this time and I don't see myself making that decision any time soon, if ever. I enjoy both Gnome and the K desktop environment, for different reasons. Much like comparing two different cars, each has their pros and cons I guess.
I do know that I'm going to have to stick with Gloria's "Main" edition for the time being as my computer isn't really MY computer, it's a family computer, therefore I have to run Linux through Virtualbox installed on my iPod, which I use as a portable hard drive.
Eventually when I buy my own pc I might even consider dual booting the latest version of Mint in Gnome and KDE, or if possible (like I said, I'm fairly new to Linux), I'd like to be able to install both environments into the same install, and just choose which session I'd like to log into, much like other distros do. This will be a while until I can afford a pc, but can this be done in Mint?
