If you really want to hack from scratch... here is a starting point:


The size is right... but it does not come with a display though the
driving stuff is there. The price is a little higher though $98... if you
buy 1000. double for 1 only :P

This one might be better, Cheaper for one:


They are $40 each for 1000... triple for one. It has a touch screen
interface, but I would guess you could do with out. It has key interface
and all you need are a few LEDs for some of the uses you mentioned. I has
mic in and headphones out (1-ip, 2-op), USB both ways, host and slave,
ethernet, com ports, wifi (some of this stuff may cost extra :) etc.

Both of these modules say the run linux, but the top is atom based and I
think you could just load something like ubuntu (for example) off of a USB
stick. The second one you may need to buy the loader because it is not an
x86 type cpu. It looks like the linux package is a free download as are
all the docs... you could look through the docs on a number and decide if
they are any good before you buy one. May even be able to test it on a
virtual machine.

The gumstix I mentioned before are definitely more costly as they start at
$130 without interfaces. (from what I can tell) They do have some plug and
play systems though.

Speaking of plug and play:

plus this:

Gives you the whole unit minus case, touch screen and everything. I think
it is basically a smart phone.
