I don't agree that Fedora is good for private use.
Loads of things are missing (mainly from multimedia) due to obscure licencing issues, which hardly exist (e.g. Fedora is the ONLY Linux distro which cannot even playback MP3 files right out of the box!), and so you have to resort to packages from
http://rpm.livna.org/ which hardly go without any conflicts with the official Fedora repositories, or build all them yourself.
There are several other distributions, mainly from small companies, which have everything in, and also some of them are 686-optimized, and as such way faster than Fedora could ever be.
Redhat is good only for those who need a stable server distro and relatively little Linux experience, so they are willing to pay for regular support- or they have a very big infrastructure and want some "your-bucks-guaranteed" Enterprise level support.
