iPhone Demonstration
So far, both my bosses have bought an iPhone after playing with mine, and my dentist is seriously considering it.
I have been asked many, many times to demonstrate my phone to complete strangers. I remember being out for a drink at a local pub with a two friends. We were in the middle of conversation when a 50 - 60 yr old lady (nice lady though) asked me, "is that the new iPhone?" (pointing at my phone laying on the table). I replied, "yes". She then asked if they could see it. I didn't mind so I said "sure". Then her entire table (around 6 people including a 60 - 70 yr old grandpa) pulled their chairs around my table and the demo began.
A few nights later at another bar upon seeing my friends all playing with my phone at my table, I had a group of college students yell across the bar, "Hey, iPhone guy!" At which I raised my phone as to say "yeah, yeah". Then they came over to interrogate me about it ... in a good way.
My dentist, upon seeing my phone, stopped working on my crown, started asking me to demo it, and then asked the entire dentistry staff to come into the room and have me demo it to them.
The biggest frustration with the iPhone isn't the keyboard. It's the fact that you can't simply use your phone anymore. Either people are intrigued by it and ask you a bunch of questions and request a demo, or they act like you're showing off when you simply want to take a call so you have to conceal the fact that you have it. And they don't refer to it as your phone or your cell phone ... they refer to it as your iPhone.
