I found it really easy, but I was pretty familiar with the terminal on Windows. I started off with Debian in December and set up LMDE for my wife a few weeks ago and it was dead simple, though I do have to be her tech support since she's not really a computer person.
I thought it would be a pain to install drivers and Steam and all that, but it wasn't. I did give up on trying to set up my printer, but I'll revisit that eventually.
Yeah, I know that, that's why I picked it for her.
