Fedora as a desktop however...I don't know...the few times I have seen Fedora Core 5/6 desktops in action, Firefox froze, keyboard input would not work all of a sudden...
Experiences vary obviously. I get none of this on my two laptops running FC6. Haven't had a single problem since February, and I 'yum update' every day :/ And my laptops (each with 1.5 - 2 GB ram) are not running a cutdown selection of services either. They are running everything.. apache, mysql, postgresql, eclipse, zend platform, nfs, vnc, cups, etc. You name it, I'm running it.
