When this year began, we were feverishly speculating about an Apple tablet, looking forward to 3-D TV sets, and optimistically waiting for the end of the cable companies’ cruel grip on our wallets.

We had to settle for one out of three. While manufacturers did release a handful of 3-D TVs, there’s just not enough content either on cable or Blu-ray to justify purchasing one yet. The heavy, expensive glasses you need to buy don’t make the proposition any more attractive, either.
