Just been experimenting with a PIC16F917 for an LCD application. 
Due to the number of segments I need, I'm not using the internal LCD controller, but doing
direct-drive LCD control in software. 
I was highly impressed by the low current consumption of these parts - waking every 16ms on the WDT
to generate the LCD AC drive, it draws just 1.6uA at 3V
Running the 32K Timer 1 oscillator adds about another 3.5uA 

PIC based wristwatch anyone..?
