I've been using Gentoo for 8 months now. I'm fortunate to have a broadband connection so emerge'ing updates is no big deal. I've got to say that my system is so clean that it squeaks. I'm a GNOME fan so there is not a lick of Qt or KDE on my system thanks to the USE="-qt -kde -arts -qtmt" flags. As for services that I run, they are limited to just a couple. I don't even run cron. I love the init script layouts, the make.conf capabilities, the config protection, and abundance of up-to-date ebuilds.
Gotta love this distro!
