I moved to --current on one of my Slackware boxes a couple of years ago just because I wanted to see whether I could do it successfully. It was on 13.37 at the time. It ran almost flawlessly up through 14.1, then I put Mint on it and gave it to my son. (The only glitch I encountered was that, after a few months, gtkam stopped working. Since I could just pop the camera's memory card in the card reader, that was No Big Deal, so I didn't even bother to find out what broke. I'm guessing some library got updated out from under the installed version of gtkam.)

I otherwise found it rock-solid Slackware stable.

I have two Slackware boxes right now, and both are running --current.

-Current x64 on my Thinkpad.
Stable 14.1 x64 on my workstation.

Stable, always stable, because "bug-free" is an ideal which can never be reached in reality in any system of nontrivial complexity, and why deliberately put bugs into that system by using -current?

Every time -current approaches a release and Patrick announces release candidates, people have found bugs, which usually get fixed for the next release candidate. This implies that -current always contains some bugs that interfere with some users' use-cases.

14.0 contained at least two problems (one regarding a particular wireless device driver, and another regarding a bug in less(1) which only showed up when invoked from tcsh), so even though releases are better than -current, they're not entirely bug-free, either.

Slackware tends to be as close to bug-free as a Linux distribution gets, though, which is a big reason I remain fervently Slackful. I've had to use other distributions for my job, and they all range from slightly worse (Debian-Stable, CentOS) to much, much worse (Debian-Unstable, Ubuntu, Fedora Core, ScientificLinux). Slackware's robustness has spoiled me for any other distribution.

Stable.

Because I've ran -current without any trouble... until gnome-keyring and NM went completely nuts without any reason.

Now I just recompile the stuff that I want more up-to-date, e.g Firefox and that's it.

-current because it's fun. waiting kde update ... :)

-current with a few custom built packages like imagemagick and vim.

Stable. I can't go to a gig, only to find out my laptop won't boot. Rehearsal/tech time is precious enough without having to troubleshoot computer problems with the eyes of anywhere from 1-30 people on you and a conductor breathing down your neck.

I use stable and Slackware64 on my laptop and Slackware x86 on my desktop and we can even buy a third pc to install current :p

Current for my gaming-machine.
Stable for my computer at work.

-current except for the kernel which i let go for a bit.
