So its kind of funny that I saw this thread because I was thinking about trying out Linux on my computer last night but gave up because I have a short attention span. I was looking at Mint because I couldnt really find anything else that looked like something I'd want.
Anything I should know before delving into this further?
I would try out elementary if you're trying out a distro for the first time. You also can look on distrowatch or some other site and see if any distros look nice to you. In my opinion, mint sucks. Unless you're using the debian version which I heard was really good. For my choise of distro I like using ubuntu, I think the reason people think its slow out of the box is because they don't install drivers, don't remove the online features (if you're using 13.10) and some other people say its bad because of its amazon advertizements in the dash. You can also remove that with unity tweak tool in the software center. Or if you don't want to do that you can install any other desktop enviroment. At least, thats how I use linux. I stick with unity because I like its feel. If you want to keep that current desktop enviroment from mint, its called Cinnamon
if you want to have it, try this:
sudo add-apt-repository ppa:gwendal-lebihan-dev/cinnamon-stable
sudo apt-get update
sudo apt-get install cinnamon nemo
I'm guessing you don't know much but yeah
or you can just try it out on a virtual machine.
