True, but does it matter *that* often

Also true, although if you already have a micro with flash, then that might not be an issue either.

None of that in V-II or Spartan-III

But what about your flipflops? I'd still be worried about them upsetting!

Not a good number to use. I *want* a Tjmax - then I can simulate the thermals of my system, with whatever heatsinks and fans I might or might not use and ensure that it is not exceeded. Or use the timing tool to derate. Of couse, this needs a good package model. Ambient temps are no use unless you are doing an average design.

Great advert :-) Believe it when I see it !
