Speaking from my limited field of view as a scientist, and administrator
of systems dedicated entirely to science, I would have to say that uptime
is a very important statistic.  Each machine's queue is loaded with about 1.5 jobs
per processor all the time and when they die, the jobs die with them
and there is the overhead of restarting and sorting through the rubble.
The more you automate this the softer the blow, but downtime sucks
and a machine that has to be rebooted for every piece of software that 
gets put on it is basically a useless machine.
