I believe this to be true. Everyone misses that feeling we all had back in 07. Including myself. But products like the iPhone don't pop up every year or 2. More like every decade or 2. Before iPhone, what was the prior "big thing"? HDTV? And look how that's been progressing. Prices have come down, TV's have gotten bigger and thinner, and we now have half baked 3D. But other then that, there hasn't been any big leap in the TV industry in a long time.
The iMac changed personal computing as did the iPhone and the iPad.
It could be argued that the iPad was an incremental step, and perhaps it was but I'm expecting a Big Bang in the near future.
