NOBODY'S EVER DONE THIS BEFORE: The most obvious visual and functional difference between the iPhone and other multimedia communications/entertainment products is the lack of a conventional keyboard.
Most operations are carried out on a touch-sensitive 3.5-inch color screen that covers almost the entire face of the device. The display is graphically transformed to the task at hand - be it skimming your finger down a list of phone callers who've left messages, checking the weather forecast, or viewing a streamed YouTube video (more than 10,000 will be available for perusal, at launch.)
The most impressive feature of the iPhone is its uncommon inclusion of high speed Wi-Fi Internet connectivity, in addition to phone and Internet access via AT&T's Edge network. This combination (and Bluetooth, too) will allow the device to "multi-task" in Wi-Fi hot spots like no other smart phone ever has, said Richard Doherty of the Envisioneering Group, tech analysts with long and deep connections to Apple.
"Say you're in a strange town and decide you want to eat lobster. You can do a Google or Yahoo search on the iPhone that finds the closest restaurant that features it and brings up a map to plot the location, then have the phone automatically call the place to make a reservation, all in just a second or two with just a couple of screen taps."
BUT NOBODY'S EVER DONE THIS BEFORE: Apple has had two years to fine-tune the OS-X-based operating system and Safari browser to run the iPhone show. But we hear that the firmware is still being tweaked on a daily basis.
So, will programs clash and crash when, say, you're listening to a tune and get a sudden urge to snap a picture with the built-in two-megapixel camera, and then try to e-mail the captured image to a friend while a phone call is coming in?
