Glass needs a usefulness boost if anything... I hate to keep saying this, but I just can't see it as anything other than an expensive gimmick to walk around with and show people. Think about the things you could buy with $1500... hell, I could build a half decent system for a third of that and have enough money left over to buy a Titan Black. These things seem to be seriously lacking proportion between price and functionality. Sorry, Google... it was a good idea, but one that seems a bit fundamentally flawed out of the gates.
