PPA is an acronym for Personal Package Archive. This lets people package  
and build applications in their own personal repositories. These are very  
similar to the official repositories (like Main, Restricted, Universe,  
Multiverse) in Ubuntu.

You can add PPA's to your sources.list file and install applications from  
there. It is suggested that you should use caution and only use trusted  
PPA's as not all will have functioning applications or will be maintained  
well.

Here is a link that you can read more about PPA's:

I have found that some people feel very passionate about this questions. I  
personally appreciate the complete Ubuntu Studio install as it reduces the  
amount that I have to tinker with my system. Others prefer to add their  
packages as required because it allows them to moderate their system to  
better serve their needs.

If you have a system that works for you then I would suggest staying with  
it. But you may try a full install once and see if it works better for you.

In some instances there are people that choose to start with a Ubuntu  
install first for technical reasons that might have been resolved in later  
Ubuntu Studio releases. I am specifically thinking about networking and  
wifi. In past Ubuntu Studio releases we shipped gnome-network-admin which  
had difficulty with setting wifi, therefore some might have started with a  
vanilla Ubuntu install before it shipped with network-manager which worked  
brilliantly for wiki. Ubuntu Studio has recently moved to using  
network-manager as well, so the reasoning for their installation process  
may not exists anymore.

Again, it's still a personal decision.
