I agree Mint is a superb distro, I had it on my main box and laptop for nearly a year!
I thought, though, after seeing Linux Help Guy’s videos on youtube to try Peppermint 6.
I tried a previous version and wasn’t too impressed but version 6 is fab – based on ubuntu 14.04 LTS, same as Mint Rebecca, it absolutely flies – especially on my i7!
Have a look at LHG’s vids – don’t mind the swearing – and see what you think!
Cheers
