I would also argue that MTBF is unimportant in a machine used for a 

I'd much rather have a machine that required minor maintenance/repair
every year or so (requiring, perhaps, that the fans be taken apart and
cleaned, or ta few TTL chips replaced) than one that ran for 3 yeasrs and
then failed in a catastrophic way (requriing the replacement of, say, a PC
motherboard or a modern hard disk).

Incidnetally, I feel this way about things other than computers. 'Sealed 
for life' bearings are a pain. I'd rather go round every month with a
