ZorinOS?

I like it, it's an Ubuntu lts with a nice theme (I wish it had grey instead of just black and white though), wine integration to run compatible windows software and it's always just worked for me.
I don't like the fact that some things are locked out unless you pay for the pro version but I think that's just layouts and stuff.
I'd say it's good but like all of these Ubuntu derivatives you're almost always better off just using Ubuntu. Even people changing from windows to Linux, I'd still just tell them to use Ubuntu.
