Ubuntu GNOME Is Now Official Ubuntu Flavour.
Till now,most of the Ubuntu users who liked GNOME Environment had to <a href="https://www.crazyengineers.com/threads/adding-ppas-in-ubuntu.61390">Adding PPAs in Ubuntu</a> to get GNOME Environment.Unfortunately,Ubuntu 12.04 LTS users were unable to feel the GNOME Environment as only Gnome-shell was available in the Ubuntu 12.04 GNOME Remix version.

I am GNOME Environment user & due to its smooth/flexible environment & easily tweakable Interface I have always loved it more than Officially Shipped Environment "Unity".
In Ubuntu 12.10 Quental Quetzal,It was possible to get entire GNOME Environment using it's official Gnome 3 PPA from launchpad,but the LTS version(12.04) kinda missed it.
Only "Gnome-Shell" don't really gives you GNOME DE feel, right ?
Ubuntu has announced two versions for upcoming release :
- Ubuntu GNOME
- Ubuntu UNITY
Now,If you're well versed with Linux Operating Systems & Environments then you would've known that pre-installed applications like Calendar,Calculator,Orca,Games & Movie Player are of GNOME,so why not get entire GNOME, right ?
Ubuntu GNOME will be shipped with GNOME 3.6 & not 3.8 - unfortunately, most of the Ubuntu 12.10 users were using GNOME 3.6, so we ofcourse demand for the upgrade !
As of now GNOME 3.8 ain't stable - Ubuntu can't ship it with Gnome3 PPA.However, you can add PPA in Ubuntu 13.04 if you wanna upgrade GNOME DE to version 3.8

Finally,
I am happy that I don't have to purge PPAs & then upgrade the distro & then re-add & update the PPAs.
But I feel that this will decrease the popularity of UNITY Desktop Environment,because from my experience GNOME is a lot matured & faster than UNITY.
Whatever it is;
Good Job, Ubuntu 👍
