I've been doing distro-hopping for years, with a special "love" for Gentoo Linux (love ended in ~2009).
For 2 years now I've returned to Slackware and here I'll stay!
Currently using Slackware 14.1 64bit. Very stable distro which comes with all the software I need working out-of-the box (just choose "full installation" and you have everything ranging
from text editors, then browsers and IM/mail clients and ending with media players).
So try Slack! You won't be dissapointed.
PS:
Just for the record: Also using FreeBSDs, but in the context of this thread, this is offtopic.
