Agreed. The F88 is an awesome device, having so many advantages over other
PICs. MY favorite scheme is the dual oscillator; the user can waddle 
along at 32K
using flea-power then switch to a high-speed 8Mhz to do some real work 
at normal
current drain, then switch back again. Add to that the bootloader 
capability, and for
0.25USD more its an incredible bargain.
