Well, you make a good point and remind me I should respond. While it is true the bigger 'Pods (IsoPod(TM) & ServoPod(TM)) can do 26 RC Servos at once, it is more impressive to know, that is in set and forget hardware.
Some day I'll have to sit down and see how many additional RC servos I could drive in software. I'm pretty certain I could drive all the available GPIO pins, for another 22 RC Servos in software, and still have processor time left over. However ostentatious it sounds, 48 RC servos would probably be closer to the "apples-to-apples" comparison.
The 332 TPU is quite a remarkable timing unit. It's also quite the bear to figure out.
I prefer the larger processors for dedicated applications for basically one reason, the large linear address space. I've just begun using MCORE for that reason, and I'm also looking at the ARM processors.
