It's a safe assumption that all software is always broke.  Read through the 
changelogs of any large project if you want to see how depressingly true that is 
or how unlikely it would be for something to be perfect.  So the question 
becomes one of whether you trust the people generating the updates to know 
whether they are needed or not.  With systems like fedora where the 
distribution's goal is to push out new/different software in the hope of 
eventually advancing the state of the art, you probably shouldn't expect updates 
to be any more stable than what you have installed.  But with RHEL/Centos where 
the goal of the distribution is stability the updates generally are just to fix 
things that need to be fixed.  The only reasons to avoid them would be if you 
have unusual circumstances like weird hardware or you think you know more about 
linux than the team building and testing the updates.
