I use Ubuntu 9.04
Which distrobution you guys running?

I will definitely try it. I couldn't install the preview version on my PC with multple partitions due to some anaconda bug. I peridically try openSUSE and Fedora every time a new release comes out, and so far they always had terrible font rendering on my LCD screen. Otherwise, I liked openSUSE a bit more than Fedora, but I must say that Ubuntu has more packages, and online help is superior.

Open Suse and Ubuntu. I use them mostly at work for squid and nagios. My home box has Ubuntu and Vista. I use Vista to run Visual Studio 2008 and Rybka 3, so it's running Vista 95% of the time. I am a Microsoft guy: MCSE, MCITP Enterprise Admin, etc... But Linux is my hot little mistress on the side.

Ubuntu 8.10
I tried Jaunty, but it doesn't seem to agree with my Dell laptop.
It's running great on my HP with KDE 4.2!

I run openSuse 11.1
Which desktop - gnome or kde? (or other?)
Gnome
I run openSuse 11.1
