Yeah, my only issue is construction. If you found a Type 4 behind an office building by the dumpster (couldn't be me), chances were good that it would still work and continue to work indefinitely. The stupid "let's shove some traces on a sheet" that Sun adopted was prone to failure in the event of slight dampness or also just for no reason.
