I am thinking about replacing regular Ubuntu 12.04 on my laptop with 13.04 Gnome - or Gnome Remix 12.10, given that the latter oddly has a longer life cycle as of now. Which of the two comes with the more updated state of Gnome, out of the box? If the version numbers of Gnome are the same in both, are there any other differences to the Gnome-Shell experience? More specifically, I am hoping for the customizations (shell extensions, user themes) to become more integrated and well-supported OOTB as development proceeds. Currently, shell extensions are unofficial self-fixes that may or may not work with different versions of Gnome 3. To be able to use them, one has to install a package that isn't easy to find. Similarly, the ability to choose user themes is tied to an unofficial shell extension. That is the kind of things I hope to see improved in the future, possibly even between these 2 versions of Ubuntu?
Ubuntu 13.04 is more updated, though not significantly once all updates are installed. "Out-of-the-box" the Gnome remix has some big bugs in it that aren't fixed until the first
The big difference is that by adding the Gnome 3 PPAs to 13.04, you can upgrade to Gnome 3.8. To my knowledge this does not work on 12.10 unless you add the
As a user of Gnome 12.10 Remix, go with 13.04 and add the PPAs. You'll be glad you did.
