It's tiny, but it's not pixelated. It's rather high-res for its size; you can't see the pixels.
> killer app?
For me at least, the killer functionality comes in the form of wink-to-take-a-picture. Especially when travelling, it's amazing to be able to take many pictures from your POV instantly without even having to really do anything. This leaves you with a huge amount of both significant and insignificant pictures that together tell a story.
How has the voice recognition in public spaces suited you over time? Based off my brief demo, it wasn't too great. I placed it at or just barely below the voice recognition on the Google Now & Siri app on my iPhone (neither of which are too impressive atm).
I don't even try to use voice when it's windy outside; it'll hardly get it right. I fault the hardware for that.
In terms of the commands, it's decent, could be better. I wish it had open-ended commands like Siri/Google Voice Search instead of being restricted to a list. Well, it sort-of does have open-ended commands by performing a "google" search. For example, in the past I've been able to say "OK Glass... Google... In five hour remind me to call Bill" and it would set a Google Now reminder. That specific feature has appeared and disappeared over time, I think they're still working on it.
My experience has been very good for colloquial English. Text messages I've sent where I've used a lot of jargon or proper names, that you wouldn't find in a dictionary, Glass understandably fails.
I shoot pool and even in a loud pool hall I can almost whisper my commands and Glass picks them up just fine. What is neat is that Auto Awesome will stitch together clips of my game, and at the end of the night I have a highlight of my match.
Glass's camera is really good at taking quick photos of things and people that tend to move before you can pull out your camera. This makes it a useful tool for capturing cute baby or cat moments as they happen.
