ahhhh but does not come with a color projector

Seems like a heads-up-display for now. Perhaps synced to a phone app, it could show you things like how many steps you've walked, calories burnt, temp, text messages. Could get interesting.

Well if all it can do is play back a prerecorded message then this seems to be nothing more than a novelty.

And before someone says, “oh but they can add features to it later” I say you get basic functionality in first and make it look like designer glasses later!
if all it can do is show prerecorded messages now, then it's pointless,

Integrating the display is the tricky bit, showing a pre-recorded video is basic functionality*

* Smart glasses basic functionality:
- not make you look like a berk
- have a means to tell you information without you looking like a berk
- fit a few ARM cores and some cellular connectivity somewhere
