I use slack as a DNS, firewall, mail server. It's the gateway for my network (about 100 PC) to reach the Internet too.
All of theses services are on a single PC. (I know, that's not very safe, I will change it soon)

I'm with disinteger on this one, had slackware 10.1 (2.6.10) as and Operation Flashpoint dedicated server

I have 3 computers all slackware 10.1 (2.6.10),

one is in my cupboard as a samba share server, it has vnc server running too so i can use azureus on it.

my laptop is mainly for surfing the net and editing my website.

my desktop is only just got slackware on it, mainly used for games, but i have to boot into windows for some of them

I'm currently running Slackware 10.1 on two systems. I do 90% of my work/play on my main system, which is dual-booting Slack/Win2k. My secondary system(Slackware 10.1) is used for researching things while working on my main system. I use my main system for everything really; checking my e-mail, surfing the net, playing games, web development, audio and graphics editing, pretty much everything. The only reason I have this system as dual-boot is because I can't get some of my application/games to work through Cedega/WINE.

I like Slack a lot; the "BSD wannabe" is my favorite Linux distribution for a multitude of reasons, and I use it on my home PC for pretty much anything I can think of ...

• The new development release of Fluxbox handles my window management needs
• I watch DVD's, mpg's, divx movies with Xine
• I listen to CD's adn mp3's with xmms
• I make mp3's with cdparanoia and bladeenc, a Perl script I wrote handles the interaction between the two
• database programming with Perl and mysql
• web programming and development with Perl and Apache
• learning C++
• Internet browsing with Firefox, from safely behind netfiler
• irc with irssi
• reading UseNET with tin
• build new kernels to try out

and I do a lot of 'other' experiments ... It's a great operating system, stable, reliable, helps me get my job done when I am working on important projects for work while at home on the weekends.

My favorite thing about Slack is the way in which one configures a Slack system, as well as the BSD style init scripts, as opposed to the System V style ones other distros use. I swear by Slack, I have a Slack "S" logo tattooed on me and I could go on and on, raving about it.

I have Slack 10.1 installed on three systems:

BadWolf - a self-assembled 1GHz mini-ITX box which I intend to use for day-to-day tasks like web browsing, word processing etc. I say intend, as there are still a few kinks that need straightening out before I can fully migrate from Windows. For which I have LQ to help me.

tanktop - a 233MHz Panasonic Toughbook. Good for most general computing tasks, and playing old Sinclair Spectrum games on FUSE. Subjectively, Slackware seems quicker on an old crate like this than something like Mandrake. Plus it's easier to strip Slack back to fit a smaller hard drive.

echoalpha - my main 2GHz AMD rig. Currently dual booting with Windows XP which I use for sequencing and other audio tasks until a few Linux audio apps I'm tracking mature for full-time use. I used the Slack partition for testing new programs before migrating them to the other two systems.

On all three systems I use XFCE as my desktop, though I used to use Fluxbox extensively.

Everything I used windows for.. Except cleaning viruses and spyware from other peoples windows hard-drives.
Listen to tunes, burn cd's, download tunes from winmx or limewire, Play Backgammon, mess around with html, surf -n- read.
I'd be hard pressed to name a feature That winblos has and Slack doesn't. If I had to, I'd say I miss 3dfibs, but javafibs works okay for me

I use it for web design, word processing and speadsheets (OOO beta- the only good version is the latest beta which roxxors), web browsing, GIAM chatting (Hate gtk looks, but i have my GTK apps looking like my QT ones), gaming (tibia and Jedi Outcast under cedega) video stuff... whatever. I'm trying to completely rid myself of the need for my WinXP partition and I'm doing very well.

I very much respect BSD, and slackware is as close as you can get without the small program compatibility. Everything just works.

I use one of my slack boxes as a Jukebox........I ripped all my CD's to .ogg format and they fill up a
8 gig partition, and I use mplayer to access them.....
it's all good and sounds great...........

IRCd
Eggdrop
IRC Proxy
Iroffer
Webrowing (Firefox)
XMMS
XChat

And everything else I can run via the Shell
Like ...
Orpheus for mp3s
IRSSI for IRC
CenterICQ for Chat
Mutt for email (5 accounts)
And of course BTDownloadCurses for BT

I <3 Slack

Oh... and am currently setting Web pages for IRC download administration and PJIRC for friends.

webber: FreeRADIUS authentication for my wireless LAN, NFS, FTP, HTTP server
wingnut: Web browsing, email, OpenOffice, GIMP, scanning, gaming (Q3, UT), video/audio editing, CD burning, DVD viewing
dipstick: (laptop) web, email, wireless sniffing, GPSdrive, Streamtuner, IRC, VPN, rdesktop, IM, XMMS
traveler: (laptop) web, email, wireless sniffing, IRC, VPN and alternative to Windows for work system
dragon: (son's) IM, web, email, OOo, gtkPod, XMMS, games
ucla: (other son's) IM, web, email, OOo, XMMS, games
spare laptop: breakage, err, testing

I use slack to solve problems...

I once used it as a desktop, and just might consider it again for desktop use once 10.2 or 11 comes out.
My desktop use is now taken care of by ubuntu (laptop) and kubuntu (desktop)... not saying slack is not good as a desktop, just that ubuntu seems to fit my desktop needs better.

But these days I use it as a tool: A need arises, drop in slack, configure, and it runs rock solid...

I'd place my trust in slack as a server OS well before fedora or anyother distro...

Well i recently found that i can run a CS:Source server using linux so i will be experimenting with that, it should be interesting

Other then that i will hopefuly be putting an Apache / PHP / MySQL setup online, mostly for development and testing/learning porposes.

Im about to go meander about and see what other games of minei can use linux asa dedicated server for

1. Personal webserver - dump documents and stuff there so I can retrive it wherever I go. Well, almost wherever.

2. Web-development

3. Image manipulation

4. Word processing.

5. Web browsing.

6. My bittorrent station

7. MP3 encoding. And sometimes video transcoding.

8. Multimedia station (audio and video and graphics)

9. Programming now and then.

10. Updating Slackware (hitting the slackware changelog every time I think of it) and tweak it till it breaks and fix it again.

Not exhaustive.

Personal laptop OS: Slackware 10. Do all my home browsing, gaming, accounting etc on this machine.

Work is dual boot between XP and Slackware 10.1, would be Slackware only but I have issues with a Ricoh network all-in-one and Lotus Notes (the world's shittiest application imho) that I haven't had time to fix yet.

I have another box on semi-permanent loan to a (70 year old) friend that is dual boot between FC4 and XP. He couldn't care less what OS he uses (currently XP) but he hates the fact that it breaks down every few weeks so I am planning to upgrade him to a Slackware 10.1/KDE system soon. I think he'll be happy.

Two Slack boxes, both -current with 2.6.12.3 kernels, (and one DamnSmallLinux box that doesn't count); one's a desktop, the other is an HTTP/FTP server. Samba for allowing a XP box on the LAN to use a laser printer, web cam, streaming audio from the "net, surfing, ogg/mp3 server on the LAN, UT2004, whatever... I no longer use Microshlop OS's at all, except for installing/repairing Windows boxes for clients.

So, to answer the question: computing, in general.
