Forget CPU speed, memory etc.. What is your idea of a really KILLER feature (built in or add-app) for a smartphone? Something truely "discontinuous".
For example, several universities are starting to use portable circuit labs which allow students to breadboard and test fairly sophosticated circuits in a mobile way with a scope, function generator all controlled with a laptop via usb. A great idea and it empowers students.
But of course most smartphone don't have that USB hosting capability (yet?).
I think something cool (since I do a lot of circuit testing) would be to have a WIRELESS voltmeter or scope module that my smartphone can talk to and display the measurements. 3 things here ... the meter being able to "talk" to the smartphone, the "sort of" real-time data communication between them, and of course the app that controls the measurement box.
