Let's get rid of the wires. Rechargeable or AA battery powered compact
remote mountable Bluetooth GPS and WX/XM radio transceivers? Garmin already
makes the G10, a little handy dandy Bluetooth GPS smaller than a large pack
of gum. WXWorx already makes a Bluetooth Weather and XM radio transceiver.

Larger screen in portrait mode (as per Jay's request)

Terminal procedures with GPS overlay.

Basically, let's say "most"of the features of FlightPrep's chart case but in
a non Windows sans hard drive format. If the screen and the memory card are
large enough, then maybe add the sectional charts. Heck, I wouldn't even
mind if I had to switch memory cards enroute. Or have multiple card slots
to add software features as your flying needs and wallet allow?

Well, what features that Garmin does not offer would you like to see?

Jay says a larger screen. OK, seems possible. What else?
