Yes, portables are certainly the exception.  My laptop does have an
independent /home and it does not require NFS for typical activities.  I
do use rsync to keep certain configurations consistent but it is a pain
compared to the simplicity of using NFS on desktop systems.

I can certainly see how someone who travels often would consider
portability to be the most important thing.  In fact I might even only
have a laptop if I was constantly traveling.  However, I am the complete
opposite as I work from home and would only travel for the occasional
vacation.

Of course whenever my laptop has internet access I can tunnel NFS
through OpenVPN.
