With the release of 3.X Apple enabled apps to use Bluetooth or the dock at the bottom to create devices that interfaced with iPhone apps... I thought of a bunch of possibilities right away but it seems like the market is definitely lacking in any actual products. I'm pretty sure Apple was getting at the fact that devices would be sandboxed to the apps that they were intended for, but I could still see someone creating a keyboard attachment. Maybe the ability to connect to a bluetooth keyboard for an email program. Like all those landscape email programs of yore. Something that would let you write drafts using a full size keyboard and then send them from regular mail. Anyone got a clue what happened here? Or anyone have any concepts they'd like to share?
