The biggest reason I shutdown, power failure.  I use checkrestart to see
if/when I need to restart something after doing updates.  If for example
I update something in the @system area, then I just logout of the GUI,
go to boot runlevel, run checkrestart again to see if that did it and
then go back to default runlevel.  Sometimes, I have to restart
something by hand instead of rebooting but not to often.  Generally just
going to boot runlevel gets the job done.

One thing about not rebooting a lot, you use cache a lot which can speed
some things up a bit.  I have 16GBs here and most of the time, it is
almost all used.  How much that helps, I dunno but if it didn't help,
they wouldn't have it doing it.  Another good side, run updates while
you sleep. 

The only bad side, more wear on things like fans and some extra dust.  I
try to clean my rig at least twice a year or whenever I notice the temps
a little higher than they should be.  Oh, pulls power all the time which
may not matter much depending on your electricity rates. 

Of course, fixing that connection issue may be a good idea too.  ;-)
