Revolutionary means (to me) it would change the way that you interact with that genre of 'thing', or change the way you live your life in some way. A car that is faster, or more efficient, or prettier, is not revolutionary. A car that is driven by a computer is. The original iPhone was definitely a revolution: it changed the way everyone made phones, and it changed the way we look at phones. The iPad, likewise, changed the way we use computers (or at least some of us). This really looks like an evolution though. The only thing on that list that could possibly be revolutionary would be NFC, since it could dramatically change the way you pay for things (note I said could, I personally don't think it's the future).
