A. Fedora is release based. Actually, come to think about it, unless you're using Gentoo, everything is release based. (Debian Sid doesn't count).
B. Fedora anaconda installer could always be used to upgrade previous versions, you just need to start it somehow. (CD/DVD kit, Network boot, etc).
However, during the development phase of Fedora 10, a new tool was introduced - preupgrade, which automates the process of version upgrades. I've upgraded a large number of F8 and F9 installations to F10 and it more-or-less worked out of the box.
C. What's wrong with RPM? Granted, back in the RedHat 5-9 days, the lack of a network front-end (such as yum/apt/etc) made life pretty difficult. Never the less I fail to see how RPM is any worse than DEB. (Actually having created both RPM and DEB packages I must admit that I prefer RPM).

FWIW, Up2date was introduced by Red Hat during the old 7.x series. (Was it 7.0?) and was backported to 6.2.
From a user's standpoint, it is not so much any particular technical features of debs that set deb-based distros apart. It is the availability of a mind boggling breadth of packages, organized into just a few centralized, well known, and well defined repositories which generally don't conflict with each other. (More packages, better organized than in the yum world.) Apt (as distinct from dpkg) is also, in the real world, much faster than yum, both in handling all the metadata, and in doing the actual downloads. I believe it can parallelize downloads from multiple servers.
Also, yum's memory requirements are insane. I have about a 60 user XDMCP server maxed out at 12GB of memory. Performance is find during the day, with 60 Gnome desktops running. No complaints about performance.
But I don't dare run 'yum install some_package' during the day. Because it causes such a swap storm that I know I will immediately get a call from the general manager saying that everyone is locked up. (Edit: I feel like I should add that I'm *really* not making this up.) It's one of the (many) reasons that I'm migrating the machine to a different distro next month.
rpm and deb may be theoretically equivalent as formats. But in the real world, the differences are readily apparent.

i wish fedora was that kind of distros that you can upgrade day by day (not per release).
Maybe i wish they ditched RPM as well, but I suppose they mainly fixed it by now
the packages are of an excellent quality, regularly above all other distros. I support our own distro here, and while being debian based, when something goes wrong, patches always come from fedora/redhat. these guys almost always have things right.
