The Pic16F877 is not necessarly better:
1.  The clock is internally divided by 4, so the core is running at 5MHz
which is slower than the ATMega163.  Plus in benchmarks the AVRs tend to
be faster, but this is probably best left for a debate on a microcontoller
news group :)

2.  The GNU C++ compiler is available for free for the AVRs

And on the iPAQ, I can see it being the quickest solution, in the future
there are a couple of really nice strongARM based embedded PCs that are
probably more power efficient than a x86 solution.

Here at SFU we are using an embedded P166MMX on our helicopter.  We are
currently cleaning up our code and should be able to release the software
under GPL in about a month (it is at the end of the semester and everybody
is on holidays).
