FWIW:  Ubuntu is quite good.  Several of the versions have an N year 
support window (3-5, I don't remember N pre-coffee).

I am migrating my laptop away from SuSE to Ubuntu.  Stuff just works. 
And when I needed to rebuild a kernel for a customer, building it as a 
correctly packaged system was simply not painful.  It was, almost, easy.

This is what got me.  apt-get is about the same as yum if you use yum (I 
had ported earlier versions to SuSE, and it was a royal pain, but yum 
makes installation and update so much saner).

FWIW:  what pushed me away from SuSE was not the Microsoft agreement (I 
had thought, before a certain Microsoft CEO opened his mouth, that it 
could have been a good thing).  It was zmd, zypp, and the other bits. 
That when logging in for the first time on my laptop (and all other SuSE 
machines), it ran this update-whatever program that consumed all the 
cycles and did nothing.  That and the updates didn't work.  It was good 
in its day, but its day has passed.  And Ubuntu appears to be better. 
Installation is easy.
