Installing/uninstalling apps in Ubuntu

[Jim Byrnes]

Is there a downside to installing apps for testing and then uninstalling 
them if you use a package manager?  By downside I mean, over time will 
the practice decrease performance or stability.

The reason I ask is for the last 12+ years I have used mostly OS/2 and a 
little Windows. In OS/2 the ini files can become bloated or corrupted 
overtime, because of broken links and references. Sometimes leading to 
performance or stability problems.
