If there is a room for improvement, more security updates, and driver supports, yes, go for it.
Yes, i do aware of this problem, that's why i stopped using it, unless i have no choice. The are putting more and more rpms into the distro. Actually, FC3 and backward are all meant for user testing. Some sort of things like software evluation and bug posting to the developr for future improvement in RedHat Enterprise.
For organizations however, a careful consideration need to be done, testings and so on. U don't wanna mess up the oganization's day to day operation.
There is of course one common problem when getting updates which is too new sometimes, which is, some of ur old programs will not work. And u started receiving phone calls. Hahaha
Overall, for my personal use, yes, im always sitting around to wait for new releases to come out.
