After thinking on long train trips a few ideas struck me for the next gen ipod...
There are rumors going around that the next gen of ipods will use OLEDs. From what i gather they use less power than LCD screens, glow (so backlighting isn't needed) and are capable of displaying in colour.
I've always wanted a portable that was capable of voice recording... as have many other people. The fun that can be had with this is off the chart. Anyway, let me move more towards the point.
Apple recently launched the iSight: a wonderful webcam, with much higher resolutions than your average webcam and a built in mic, that interfaces with the mac through a... firewire port.

OK here's the idea.

what if apple was to allow users to connect an iSight with an iPod. It would be a true portable webcam, and the iPod's screen would be just the right size. It would be a lot like a built in mic only much more cooler. Thats it folks.

Cheers
