I am a new member on this forum so I don't want to start either a flame war or get any hate mails from you, but, I will say this: I prefer apt over yum for many reasons. But, the simplest of them was the fact that all the downloaded debs are available in one single place: /var/cache/apt. So, basically, if I have to update multiple systems on my "third world" 3G connection, then I could achieve it very simply: rsync the deb files across all my systems.
With yum, I have to create a tar/gz file of the "ENTIRE" /var/cache/yum folder because the RPMS are spread across multiple sub directories and then copy that tgz across to the other system, then, untar/gz that tgz file and ... the mess goes on for ever.
Also, I came back to Fedora after almost 5 years being with Ubuntu. And during the initial few days I had a "yum shock" (like culture shock, etc) because yum just did NOT feel intuitive.
Although we are not discussing the GUI front ends, but, I will say this: Synpatic was a FAR FAR better package-manager GUI as compared to pkgkit or whatever it is called in Fedora. I mean pkgkit is just plain PATHETIC.
As an aside, I was an avid RH user till about 2005. In 2005 a friend "gifted" me an Ubuntu CD. Ubuntu installation felt like going back to Mandrake (anyone even know that system anymoe?
) So, I installed Ubuntu on all of my systems. And I wrote scripts to "make it sane". And it worked fairly well ... but, I always hated their choice of apps and how they "linked their apps together." So, removing/uninstalling app-X required that app-Y and app-Z also be uninstalled. And then, there were stupidities like trying to remove some absolutely inconsequential, random app that you absolutely never use would mandate that you uninstall the whole system. And all that brown and orange was like making me all psychedellic and all.
And then, by 2009 it was starting to get obvious that Ubuntu and I were not meant to be together. Ubuntu wanted to look and feel more like Mac OS X while I craved for raw Linux with X and a useless desktop-manager (say GNOME). Then, by late 2010, it was obvious that Ubuntu and I had to part ways. Ubuntu wanted to load my tiny, puny little laptops with more and more krap: compiz, mutter, clutter, unity, diversity, equality, and god knows what else. So, I figured I would go check what Fedora had to offer. And immediately after "live-booting" Fedora 16, I felt at home, back in the arms of redhat based distro: the first and most obvious thing ... KRAPPY FONTS. It was love at first sight. Within a matter of few hours, personal data spread across 5 systems was backed up and all those systems were reinstalled with F16. Ubuntu was gone from my life before dawn.
On a more serious note, I am using F17 on all my systems because the "default" fedora distro comes with GNOME 3.x. The day Fedora "invents" its own desltop-manager/GUI I will go out hunting for a new distro ... most probably Debian Testing.
