The iPod began with Toshiba developing a 1.8-inch hard disk drive; now the iPhone with a seemingly simple innovation in touchscreen technology, the ability to register more than one touch at a time.

An iPhone adds a high-resolution LCD, near-desktop-equivalent programming environment , gigabytes of NAND flash and a stack of subminiature radios to the package of course, but it's that touchscreen that will allow you to operate the unit one-handed at arm's length, mousing and typing with your thumb and forefinger. It gets the user out of the texter's pose — crouched hands together, head bowed like some cringing introvert. Now we can strike a heroic pose! Chicks will dig us! Our bifocals will get a rest! Huzzah!
