I like agree with what you're saying, and I want to take it to the big picture:
1. Invention of the computer - Size of a room.
2. Miniaturization of computers - Desktop to laptop to tablet to smart phone, next wearable and after that next nano
computers (probably inside us, just would hate that myself, because I would hat to have to see the bill to get them installed or removed if they break!)
How we interact with them:
1. Tactile - Keyboard, mouse, gestures
2. Voice - Siri (it still needs work, but it is getting closer)
3. Augmented reality - Google Glasses / Contacts, next Holograms w/ gestures
4. Virtual reality - Neural Interface
What is after that - ? Trans-humanism - Cyborgs, AI
I think that the watch and other wearable computers are a good idea, and part of this transition to putting computers out of sight out of mind. I only worry they will only be here for a blink of an eye. I think Apple could do it really well, just are they going to put something out into the market if it might be gone in just a few years, or months?
Remember we have went from an iMac in 1998 to an iPhone in 2007
I do see it happening as a way to replace our phones. Just I can't figure out a good way for the camera... any ideas?
