>I understand where you're coming from, but people have the exact same problem with Windows (and maybe Mac also; but I don't have much experience with Macs).

No, they do not have the same exact problem of package managing. Preferring XP over Vista/7 whatever, is not the "exact same problem".

>I personally LOVE LOVE LOVE that all my apps are updated by the same program. Instead of the Windows/Mac way of each app running it's own updater.

Well, Mac now has the Mac App Store, which handles updates for App Store installed programs.

But the problem is not about all programs being installed by the same program. It's about installations being transparent to the end user and not wrecking havoc. Also, not being inter-dependent.

Even Mac apps that update with their own updater, are autonomous units. At most, the app itself breaks.
