I've been using Linux for 13 years now, and I keep coming back to Slackware for several reasons:
1. Slackware packages and base kernel as installed is for 386/486 processor - so I can use it with older hardware out of the box.
2. Slackware is the best integrated distro -- I rarely have any problems building apps from scratch that are not part of the distro. I can't count how many times I've pulled my hair out tracking down prerequisite compatability issues under other distros - including commercial unices (Solaris pisses me off sometimes.../opt/sfw - bolloxed - who thought that up? A misapprehension of the unix filesystem standard imho).
3. Configurations are easy cheezy - and use standard tools for the most part where they are automated. I am not a big fan of becoming dependent upon GUI tools for system level configurations (you got to get down on the iron oxide if you want to learn the ins-and-outs of the system).
4. With various installation methods it is easy to hack together a marginal installation using existing tools that would certainly fail under other distros without major development work. I've installed from floppies, hard disk, parallel port zip drive, and cdrom.
5. Best mix of applications that I use (I am a developer - so ymmv). Most cutting edge stuff I want - not present or difficult to come by in other distros.
6. It's got slack. All hail Bob:
Code:

7. Package system is based on tar. tar is ubiquitous...so I don't need anything special to install packages - or peer inside packages if I need to - regardless of what system I am on. Claro.
8. It was my first distro way back when...it just fits.
If nothing else, I hope this was entertaining for you.
