WHOoOooooo. "FULLSCREEN ADDS." You can't do this on the web -- even though way more capable tools have existed for some time, which are widespread... Oh, we built it in HTML 5, a markup language with simple multimedia extensions... WOW! Amazing, here's a simple interactive add from 5 or so years back. Jobs is a Liar and what's worse, is he's taking us for idiots.
I don't block adds on my Macs, I never have! I understand that sites needs their income. If any add annoys me, I resize my browser to cover it. If I see an add in a free App I downloaded, I delete the app if it's crap, or in a rare case if it's good I've bough the full version. But now, since there's a chance that paid apps will contain adds, I'll just need to be more careful about what I buy.
