iPhone and iPads, moving beyond apps

While app development will continue to bring new fun and useful applications to the market -- this will be an important year for Apple in another way. Hardware paired with applications will further spur advancements in using the mobile phone and tablet as a user interface for control. Picture anything that today has a mediocre display screen and simplified horrible user interface -- now you can use your device to control instead. A truly universal remote -- not just for TV and AV equipment, but really anything that can be remotely controlled or interfaced.

What have you seen already out there? What is coming next?

digital cash

it is the next big thing.

I want to be able to give you cash, as easily as it is to take a 20$ bill out of my wallet and hand it to you.

We are there, the technology allows for it. Who is going to do it?
