Yeah, modern versions are a bit simpler. I can manage my Fedora system without ever touching the command line, because the package manager handles all of that for me; I just need to provide the correct password to complete any install or update.
I should also note that the package update runs automatically and lets me know when there are updates and/or patches available for installed packages.
Other than the GUI differences, it’s pretty much exactly like software update on my Windows XP and OS X boxes. (The only exception is that WinXP doesn’t prompt for password for the install.)
