> Why anyone thinks this is notable and not disappointing is exasperating to me.

Normally I'm the kind of person who has a bias against things not "fresh" but this one doesn't phase me in the slightest. I suspect it's because NY-style pizza re-heated in this matter (or even as next-day leftovers in a Hot oven) are damn good! Something about it, it comes back to life just perfectly to me.
