Hi Owen,

we did look at the PIC12C through PIC18C and generated the LPC900 family.

If you want to have a look at the LPC935 and compare it with the PIC
you will find quite some competitive features also on the Philips
8-bit device. In particular the pricing combined with analog features,
Real-Time-Clock component ...

or a family overview here:

This is a different ball game and you mentioned it yourself, the PIC
and the LPC900 are great I/O processors, the ARM architecture is not
optimized for I/O handling (although it is SO MUCH BETTER than DSPs).
It is optimized for data throughput at low power.

You combination preferably with a LPC900 device instead of the PIC ;-)
is totally in line of what we are seeing. A faster high performance
CPU for the math, control, algorithm, what ever you want to call it
and a small I/O slave processor that can stay alife with very low power. 

Regards, Robert
