Yep, I've been playing around with it a lot lately.  I think I like Mint with KDE the best - but that's the cool thing, like you said, the modular approach.  You can go Cinnamon or MATE or whatnot for the desktop.

I'm not fully entrenched yet but I easily could be.  I leave Linux as a very important option for myself for the future.

I agree with mylemonblue that the driver compatibility is amazing now, along with the ease of use and familiarity of it all.  With most distros you can figure it out very quickly because it has similarities with the Windows Desktop.  I'd venture to say that Cinnamon is probably the most familiar (but with the least amount of options exposed).

I am running Windows 8 primarily and was kind of forced in because I built a new rig and needed 'doze for a few things, mainly Poser :)  After gutting it out, it runs beautifully here :D  Ultimately, I wish it was more like XP so depending how MS evolves will determine which OS I choose in the future.  But that doesn't have to be for a long time yet.
