Another thought, in order for identification of people (outside of facial recognition) to work correctly, there would need to be some background processes running. Or, the person would have the app running at all times, to update their GPS position. Could be problemsome if you're in a building. As someone else said, this would certainly kill battery life.

Yes, the background processes will have to be a part of it, and it looks like this will be limited to the typical social networking sites, so it won't be a limitless search option.

As to battery life...let's face it, the only way to really conserve battery life is to leave your iPhone at home turned off.

It depends how they implement it and if it will really be that useful at this time for the things I do.

Maybe Apple and these companies should take a year or 2 off of making new and more powerful phones. Instead work on some battery technology to power these things for more than 4 hours.

Why?

Isn't knowing when they are brushing their teeth enough info? Is it necessary to watch them too?

That's a common perception of Twitter. Can you say FREE TEXTING? That's what it is.

[ctt1wbw]

Yes? And how about Leaksville, Stony Man, and Cavetown?

Eh, not been there yet. There are some people with iPhones in Harrisonburg.

Where are you?

I will most definitely use it. It will take people some time to become accustomed to having someone point their mobile phone at them and not get a little creeped out...
