Is there any reason to believe that this actually happened and isn't just an Apple employee feeding PR fluff to MacRumors? It's essentially unverifiable.
"You can get good PR by giving your customers free products." This is worth reading?
Think about it: if Apple put out a press release saying "we're awesome because we sent this guy a free iPad 2", everyone would (rightly) think it was crass.
What (allegedly) happened here is far classier.
disclaimer: I wrote the article, and I believe it likely to be true, but can't verify it for certain, unless the Apple VPs or guy who-got-iPad steps forward.
