Neil tipped me off to the video that Apple has on their home page. It's a 25 min. tutorial of how the iPhone works.
The demo shows a lot of the contextual power of the UI. You have the right buttons that you need when you're performing certain actions. This seems like to be the biggest problems with most software.
Things I liked from the demo:
- easily adding a caller (conference) to a call - this seems like one of the things that regular phone systems never make easy
- different functionality is accessed depending on the orientation of the phone (vertical or horizontal)
- pinch zooming in and out
- they only mention Google and Yahoo as search options. Poor Microsoft.
- my Treo has SMS message threading. But the iPhone UI shows both parties in a bubble talk format
- the biggest problem with the demo, is the unbelievable speed that the internet is accessed. I'm sure it'll be much slower in reality
