What you see here is a fairly interesting video (btw, thanks Crunkgear). Someone has hacked a real keyboard onto an iPhone. Cool right?
Thing is, this is a glimpse of the future. Not the Macworld '09 future, more like the WWDC '09 type of future. The iPhone docking plug will kind of take a reverse role where it will now connect to peripherals whereas before the iPhone was the peripheral.
You'll plug in a connector (or UWB if you are into that type of thing) into a monitor. Keyboard/Trackpad/Internet of course will all be wireless. Yes, the iPhone is your computer. Your netbook. In less than 1 year. Cortex A8, PA Semi.
