I own a Glass, and I have to disagree, the camera was a very large improvement over using your phone. Hands free use and no lag between wanting to take a picture and taking a picture (winking to take a pic) make a huge difference in utility. I got some great photos that I couldn't have gotten otherwise while traveling with it.

Too bad it didn't have many other uses, and made being out in public kind of awkward.

The press made a big deal of the camera creeping people out, but in practice, the reaction was much more curiosity and interest than fear. I think the press just wanted something to write about, and in the absence of revolutionary abilities and interesting use cases, they wrote about its perceived flaws and did a bit of fear mongering.
