WOW
great thread!!
One thing 
I have learned since yesterday....the rasp pi is not truly open source..i guess some elements are closed.


This is a deal breaker.


I need a platform which if i end up making something cool, i can transfer it 100% (software and hardware) to a pcb.


So....looks like i need to look into those TI soloutions!!! 

Thanks!

That said however it's not the last word in this space - TI has been providing embedded boards with more I/O and more modern processors for several years and isn't resting on their laurels.

A low-cost Beaglebone with similar capabilities is right around the corner and is expected to cost about half that. See more about it here:
