I can see the obvious utility of it, but I don't like the idea of experiencing the world through yet another filter of manufactured semi-reality. It's almost like we'll be forgoing immediate experience and skipping straight to nostalgia- instead of enjoying the immediate experience of, say, a ball game, we'll record it and then instantly appreciate the memory of the recording or something. Also, as Humanadon pointed out last week, there are a lot of obvious opportunities for misuse that'll be really hard to crack down on without some sort of codified new etiquette. Stranger things have happened, I guess. And on that note, while the benefits are easily identified ahead of time, a lot of the pitfalls will only be clear in retrospect when the product has been hacked to do all manner of crazy shit. What about the potential for hijacking a pair of somebody's glasses? Hacking their interface, recording their life? Seems like the potential for disaster jumps tremendously when we're invited by a product to experience everything through that product constantly, in a way not even approached by current smartphone tech. It's neat as something to read about in a novel, but horrifying in the implications of real-life use.
