I see most mock up using any new soft cocktail but rather just piking existing apps in a wider screen.
I really doubt Steve would be delaying the device and get personally involve for just a wider screenn.

Can you please start a new mockup with a cool mobile collaboration system , lets say something way much better than email, to annoy RIM.
I think all this buz around the interactive Album is more to hide the mobile collaboration features.

Wait and see.
