Observations

My partner for this was Andy Jordan

We left NYU around midday and went through Soho.

For the most part we saw people using phones, which at this point do not seem to require much concentration, it is something people do mindlessly. Clearly the goal is to contact people, which seems to happen effortlessly.
We went into the Apple Store where we saw people interacting with a variety of devices

Clock Radios: One person
Many of the people when interacting with them would often press the largest button on the device no matter what it did. "Eject, On/Off Volume". We both observed that they kind of "pecked" at them.
Wireless Checkout: Two people
Some Apple merchants were checking people out with there purchases. The transactions took about 120 seconds. I think it works well because the buyer does not have to make that trip to the Cashier. I can say for myself I have walked out of line (especially that line) several times putting my purchase back. This device helps to eliminate that impulse.

Genius Bar Line Queue: Multiple people
The line queue at the genius bar is managed by a sales associate armed with a laptop. users go to him and check in which takes about 10 seconds. This information is passed on the "Geniuses" which call up the people in the line. This allows people to queue in a more casual manner. Instead of having to physically stand in a line. They can mill about, saving energy.

Back on the street:
People listening to ipods and using their phones. Maybe it would be more interesting if people were lolly gagging in the warm weather but most people were moving about their business, not doing much
