I am going with the optimism of the OP.
As soon as I saw the special announcement I sold my Kindle. I am definitely buying the 64GB non-3g version.
My iPhone is already jailbroken and can multitask and tether (BT or USB) so I plan to use it's 3g connection for the iPad.
Split screen would really open up the possibilities. Maybe someone will even write an app to take bluetooth data from Garmin's new EcoRoute ESP:
