Don't expose GPIO directly. Soldering stuff on it can potentially ruin the phone. Have it be connectible to a breakout board and let that board be hackable.

Also let me connect my phone to a monitor and keyboard and use the thing as my development platform. All in one.

Maybe a modular breakout board connectible to the IO port would be a better startup idea.

I've never programmed for mobile devices but are the operating systems open enough to let it be possible to write a drivers for these things?



I'm hoping that we'll have that with Ara. It's PCI-E like bus means you could have a GPIO breakout module for dirt cheap.
