I can't be bothered to scour the datasheet for the differences between the atmega328 and the atmega328p chips 
What, essentially, are the differences (besides £2)?

Thankfully nothing inspires the rest of us more than your lack of motivation 
The P stands for PicoPower, a brand for a technology for minimising standby power consumption. There are other differences as outlined here.

It's 1AM here I like a good read before bed, but not an Atmel data sheet...
Cheers for the pointer. That other thread answers all my questions, including how to modify avrdude etc to get a non-p working with the arduino bootloader.
I think I'll stick to the P version though, as I like the internal 1.1V ref which is part of the BOD system that the non-P doesn't have.
I bought a bunch of the non-P ones. Once I figured out how to get the Arduino uploader to recognize them, they've worked out great. Didn't realize there was a difference till after I had them and went to program them. I just bought them on a whim when I saw the nice price.
