I installed Fedora 7 Test on my home PC a couple of weeks ago, and encouraged by its smoothness, and wanting a clean upgrade to OpenOffice.org 2.2 and Gnome 2.18, rolled it on my laptop, too. Pretty nice! Apart from those upgrades, I got:

These might seem like minor items, but all of them improve daily usability, and I much more prefer regular small improvements to huge changes, anyway. OpenOffice.org 2.2 actually is a relatively major upgrade, with support for dual screen mode in Impress (finally), and improvements in the already-good PDF export functionality.

Only two bugs that annoy me (and I'm easily annoyed), both new, but then again, many others went away:

Absolutely no problems doing a yum upgrade, but I had two things going for me, so y'all take your own chances: I've done this many times before, and I've used LVM-managed volumes for a long time. If you haven't, or don't, upgrade using Anaconda or risk not being able to boot afterwards.
