I got one of those iPhones. It’s pretty sweet. (Jan 21st 2007)[photo by me]

The patent application drawings for some sort of touch-sensitive Apple MacBook-looking thingamajig (May 5th 2006)are most likely the starting point of what turned into the iPhone: the Safari Pad. See Mac Rumors for more info.

[update] MacRumors has reported an Apple tablet/netbook will be unveiled in September 2009 and launched first quarter of 2010.
