I've been a long-time PCLinuxOS user. I recently hosed my PCLOS install (don't even ask, LOL) and decided on a whim to install Mint after reading about it on Distrowatch.
Simply put, I think it's great. This is the first distro to correctly set up my graphics card and widescreen monitor to run at 1600x1200 without me having to resort to manual configuration.
It's got eye candy but just enough to give it a polished, professional look. The selection of apps is good. From what I've seen here Mint has a thriving user community.
I like it well enough to postpone (perhaps forever) my reinstall of PCLOS.
