Agreed I've only seen 3 Sun hardware failures (I'm talking about sparcs) in something like 15 years (not counting things like disks or whatever). One was an IPX, that had a motherboard battery die and was easily replaced, but took some work to figure out how to rewrite the prom (after 17 or so years this is still running), another e450 that someone had modified to 'make it faster' and it kept blowing some CPU bridge-thing, and another ultra 1 with an actual logic board failure (it was 10 years old by that point though). as an aside I've thought about putting a bigger disk in the IPX just to see how long it takes to make a release. My netra T1 takes 24 hours and 5.5 seconds to make a full release (including X). Based on absolutely no calculations at all I'd guess a month and 5 seconds.
