Since I am a die-hard Apple user -- use iPods, iPhones, iPads, MacBook Airs, MacBook Pros -- I thought to share a few innovation tips to the guys at Apple tearing their hair over what new features to add to their upcoming iPhones that will keep the competition at bay.
Here are my top suggestions -- have an expandable external keyboard and screen. Let me explain and expand that.
The iPhone screen of 3.5 inches can stay that -- but you can have a folded screen that will expand in a fun way when the user needs a larger screen, say to work on that document/spreadsheet/presentation while waiting for the flight or inside the flight.
Oh and the user will of course need a full-sized physical keyboard as well. So include a full keyboard which nicely folds into the back of the phone. The material needs to be thin yet sturdy. Carbon fiber or carbon nanotubes might do the trick.
You all of course know about the ever expanding storage. So I need not advise you to include 128 GB solid state storage going up to 500 GB and even Terabyte class storage in the near future. The users will find a way to make use of all that storage.
They will download and store and watch movies on those expandable screens.
