If you can wait until November or so, you should be able to get something 
much closer to the power of OMAP and the price of a dsPIC board at the same 
time:

It should be interesting to see when it is at final size if it still has as 
much GPIO as the current board (the promise is for 16-ish, but it looks like 
the alpha board has more).

If you can't wait, I'm using one of these (ARM-9 @ 400MHz and ~ double the 
price, much more embeddable though) for over a year now:

The CPU module itself is a third the size of a credit card, but you need a 
base board to make use of it.  There are different form factor modules (like 
one that fits into a SODIMM socket).
