You will get comments both ways on this, but I have put lots of people on Linux Mint and they never once had to use a terminal unless they wanted to. Make no mistake, what you can do in a terminal is magic compared to what you can do without it, but you can survive just fine without it. I would suggest also looking at Zorin, and if you really want something different I strongly recommend Bodhi. Most of the distros which are easy for new users are on a Debian or Ubuntu base (Ubuntu is on a Debian base, but a lot of people forget that).
