A lot of power users has claimed about the loss of productivity due to this Unity or Gnome shell interface. It seems true because nerd hate changes, but good thing is that – if you give Unity Desktop a try – with the shortcuts and new features then you may have to withdraw your previous conclusions about the Unity (and Ubuntu).

VLC is the most popular ‘free and open source’ media player. Since, VLC can play a variety of formats – it’s recommended to have it on a GNU/Linux distributions. VLC is simple and easy to use and it has a lot of features – for simple users as well as for advanced users.
In Ubuntu 12.04 LTS (precise pangolin), a media player is installed by default but you can’t expect the default media player to play all kind of popular multimedia formats. So the VLC i.e All In One music player is required! VLC 2.0 is the latest stable release, which is already there by default, in Ubuntu 12.04 package repository.
Installing VLC on Ubuntu 12.04 LTS
Open Ubuntu Software Center and search for VLC and install it in a couple if click, or you may use Synaptic Package Manager (if you prefer package manager over software center, but you will have to install it first because it’s no longer a default application in Ubuntu).
Or you could install it in one command (open a terminal : Ctrl+Alt+t) –
sudo apt-get install vlc
Note : You must have proprietary media codecs/packages installed, in order to play various music/movies files. Better checkout this post explaining the common things to do after a fresh install of Ubuntu 12.04 LTS.

12.04 is a LTS (Long Term Support) release so if you wanted a stable version of Ubuntu with longer support (that’s natural -> many people are screwed due to the frequent release cycle of Ubuntu) then you should stick to 12.04 LTS unless there is any specific reason to not.
Here’s an screenshot of Ubuntu 12.04 LTS : looks pretty similar but there are lot of new cools features in Unity, specially the new HUD (Head Up Display, want to checkout – hit Alt key).
The new version of Ubuntu has a lot of changes and new features – specially in terms of performance and Unity has also improved a lot. Gnome shell interface has improved but if you want KDE or Xfce or something else, no problem. The default desktop may be unity but you can use whatever you want.
