I should also note that while I didn't run into this problem, I have friends with brand new PCs with USB 3.0 and they found that they were unable to use their USB ports. This also turned out to be a known bug, but there's no permanent fix for it on the horizon. You can, however, dodge around it by turning off your PC's ability to suspend operations. You can do this with the following command from a root terminal:
options xhci-hcd enable=1" >/etc/modprobe.d/xhci.conf
It may not be a pretty solution, but it is a working one.
On the other hand, there are some really neat, new features in Fedora that do work well. I have to say though that they're going to be more exiting for system administrators and developers than they are someone just running Fedora at home.
Easily the most important of these is the arrival of of Simple Protocol for Independent Computing Environment (SPICE). This is a desktop presentation service protocol, like Microsoft's RDP (Remote Desktop Protocol) and Citrix's ICA (Independent Computing Architecture), that you use to run thin-client desktops.
I can see SPICE being very useful in schools or anywhere that needs centralized control or inexpensive desktops. I'm looking forward to seeing how SPICE works out in the real world. I suspect it may prove a new and interesting way to get users on a Linux "desktop."
Fedora also includes a new interface: MeeGo. This is the interface for the MeeGo operating system, which is meant for netbooks, Mobile Internet Devices (MID) and embedded devices. While not as well known or as mature as Android, MeeGo shows great promise. By making it available on Fedora, developers can develop applications for MeeGo.
Another interesting feature is you need not run Fedora at own on your own desktop or server. You can now run Fedora on the Amazon Elastic Computing Cloud (EC2) service.
Taken all-in-all, I think Fedora 14 could stand some more quality assurance work. That said, since fixes arrive at a fast and furious rate on Linux I imagine this new Fedora will be up to snuff shortly. In the meantime, Fedora remains an excellent choice for developers and Linux enthusiasts.
