PC side uses more than 5V (12V I think), good thing a PIC can take a beating.

Jury's still out on the beating... I toast them at regular intervals doing far less nefarious acts to them.... However, they are, on whole, much cheaper to replace than arduino boards.

As far as the 12v tho, this 16f1829 chip I'm using now has been a hoss so far. And it started life as a PICAXE20M2. So when I first flashed it, it was with a home-made serial cable with no MAX232 or anything. Just straight out the serial port to the chip, so I think some chips will handle it better than most think...
