Part of me really wants one. The other part of me is concerned. The concerned part is my developer self. I am having a hard time not seeing this as extremely limiting from an interaction perspective. All I am seeing is GPS and text input (from speech). I'd imagine there will be an accelerometer, but I couldn't imagine asking users to jerk their heads around to point at something. If it came with a glove that tracked a hand or something, I'd be less nervous. If this takes off, everyone will get one. It looks like the future. Many people already feel they can replace their computers with smartphones, what if they replace their smartphones with this? If I was an average american and didn't know better, I'd let me 5 year old computer continue to age, chuck my cell phone, and blow my technology budget for the year to get one of these instead... It's a device that as far as I can see has no decent ability to capture pointing. How do you scroll in it without looking like an idiot that talks to yourself in public?
