Opamp is a REALLLY nice feature, i wasn't aware it was existing in one PIC.. but only voltage comparator & ADCs. Sure you could hack the voltage comparator with some feedback resistor, but my tests never give any good results... well not even close of what you should have with a op-amp.
The Asynchronous PWM feedback (and 2 phase PWM) could be nice for some DC-DC converter, Motor control and for sure, some others.
2 full independant analog comparator.. is a nice feature as well. There's also the REFCON and VRCON register which seems to add some nice stufff...
There's also something i want to test.. the built-in voltage regulator..
Don't worry, i did'nt read the whole thing really carefully 
Down side.. no USART, no MSSP... Oups!
For analog stuff and power management, i think it's a really nice PIC.
Time will tell...

It's not a bug, it's a random feature.
There's no problem, only learning opportunities.
