Doug, while I agree regarding performance and backup, I don't know if a 
agree about longevity.  At least in principle, wear leveling should give 
you a longer life on a larger file system for the same volume of data 
written, should it not?  What I will grant you is that the SD cards in 
rPi's that I have lost usually was not due to wear, but due to power 
transient and those kinds of catastrophic events.  However, all else being 
equal I think there is a case to be made that increasing the file system 
size.  Am I missing something?
