I would like to throw in the Cypress series of PSoCs (Programmable 
System on Chips)
Its a 8bit uC plus some digital and analog blocks that can be 
interconnected like a FPGA, all in one single chip.
Its very flexible, and tools for assembly level software developpment 
are freely available.
I dont think that the gcc can currently compile for it as a target 
though.
Why this interesting in my opinion:
Selfmade keylock-logic ala iphone slide, so we dont wake up 
continously the samsung main CPU when worn in a pocket or such thing. 
only after the slide, we generate the interupt.
We are free to develop our own logic.
More Info: http://www.cypress.com/capsense/index.jsp
BTW: this is something that might easily be retrofittet to the Phase 
1 devices, once available.
Cheers,
Thomas
I think the current Ipod nano uses them aswell for the clickwheel.
