This is ok for *concept* testing, but it won't work for "will this actually
work on device type <x> out in the field?" if you look at the number of
strange bugs that only affect certain hardware variants - like, "this
works on MX, but not on QFX".
Otherwise I agree, having virtual labs is good, running performance POC
tests on particular devices is good - but it just won't catch all the
nasty surprises you hit at upgrade time.
