OK ... this is silly
CentOS is an Enterprise distro and works great as a workstation. In fact, it is just as good as Ubuntu for a desktop. I would argue that a stable, supported for several year desktop is much better than a distro that upgrades every 6 months.
I have found just that.
I was introduced to linux a couple of years ago by way of FC5 (known about it for years, always wanted to migrate, dabbled in RH6 about 8 years ago and dropped it). I was supposed to get CentOS 4.4 but got FC5, allegedly -devel. Big mistake, I had it removed and CentOS 4.4 installed after a couple of months. The stability, the lower number of updates, reduced to effective nil dependency hell (provided that I stuck with the repo stuff, and even then many outside stuff) and long-term support was what attracted me. The 6 month treadmill was one of several issues I had; why spend 6 months installing and fighting with a system, only to have to go through the trouble of reinstalling after 6 months and starting again?
However getting my "new" printer (about one year on the market and had it since December 2007) to work on my desktop under 5.2 as well as getting, then keeping keeping wireless on my laptop using a 4 year old PCMCIA card were deal breakers.
I currently run 3 computers at home, one on the same box that got the 4.4 a couple of years ago and now upgraded to 4.6. The other two ... I had 4.4 on one and the other is a new acquisition, and installed 5.2 on both, and within a month I had to move to Ubuntu (aaaarrrrgghhhh-lee. I will be moving to F9 soon if things work out, Ubuntu is a strange breed that works, with a consumer experience virtually identical to what I had under CentOS with the exception of stuff that works with no trouble and a few nuances, but ... something rubs me the wrong way. Things like the Ubuntu customizations to the Gnome menus and the fact that the default user is defacto root while root is relegated to uselessness (including not being able to log into its own desktop to take advantage of the gui admin tools!)
Long and the short of it, I would rather keep up with CentOS, made a rash decision to use Ubuntu 8.06 since it works and has the saving grace of being LTS, and will look into Fedora 9 since I'd rather be running a(n albeit small) Red Hat farm instead of a mostly Ubuntu/Debian farm.
I still agree that CentOS is a robust and highly appropriate desktop. Just getting it to do basic things like wireless and printing (forget easily, just at all) need MAJOR work from upstream. Oh well, I don't pay site licences and CentOS strives for 100% binary compatibility ....
