Nonsense. Everyone I've talked to about Glass has suggested a new use that I haven't thought of yet, and I've only met one person who wasn't excited about the project.
Everyone I've talked to about smartwatches, on the other hand, doesn't understand. "Why? What can it do that my phone can't?" "But I already have a clock on my phone."
This sentiment is mirrored in the tech media. This might be anecdotal at this point, but I'm predicting a flop for watches and a lot of wasted time and money.
But then, maybe I'm wrong like I was wrong about tablets before the iPad started selling.
