It kind of funny that I started using Linux in the late 90's when there were few options and now we have loads of them. I've tried Unity and it would be awesome for a tablet but it doesn't feel right for my desktop. I was a big KDE3 fan but KDE4 just isn't do it for me. Gnome shell I think will be killer in a few short years but right now it is merely showing its budding potential. Linux Mint 10(Maverick) is my sweet spot. I keep returning to it like a guy who ran off an awesome chic because there are too many options out there. Well I'm back for good. I'll stay here for the next couple of years. If I find an awesome ubuntu tablet things might change but the sweet spot is always there for me. It runs perfectly and no hardware issues. What is the Linux sweet spot for you?
