Google Glass. No. Seriously, no. Please don't. Sergey Brin looks like crap in them, and so will you.
We don't need or want yet another unnecessary piece of hardware that does what a cell phone does, and makes us look like a moron at the same time. Besides, why pay $1500 for something that begs for a mugging? Something that will be outlawed in cars before you can say "distracted driving"? Something that sits on your face like a lopsided tumor?
It doesn't make you a cyborg. It makes you a dork, and hat's coming from a self-admitted nerd and geek of the old school. Think of the children. Just say "no" to Google Glass.
(And, by the way, the first Glass wearer at a neighboring urinal who turns their head to televise my junk will, shortly thereafter, be broadcasting the view from inside their own rectum. Caveat emptor.)
