Use Ubuntu at work. Waiting for drivers to catch up so I can use it on my home PC.
2 gentoo servers, ubuntu dualbooting on my laptop.
Six Debian and one Ubuntu server at work, one Ubuntu server at home.
No clients as yet.
I use 2 distros/
Fedora 8 (moving to 9)
and Ubuntu - even my partner can use it!
Fedora is great for Web Server stuff - tried it with Ubuntu but it wasnt as easy as Fedora..
I'm on Ubuntu. Started on Mandrake, had a brief fling on Linspire then Ubuntu. Does everything I need and more. Been on broadband now for about 6 years with no anti-virus software. Try doing that on Windows :-)
Ubuntu, Debian and SUSE. However starting to fall in love with OpenSolaris
I personally use Ubuntu most of the time, but I like Mint and Fedora as well.
Started using Ubuntu for work and home, just downloaded a puppy from the net, looked like it needed a good home
Does FreeBSD count??
I run an ubuntu server hosting squid at work and a OpenBSD pf firewall to seperate the wireless network from the curriculum network so that the students can hook up their insecure laptops to the school network.
