Upload & Sell: Off
I've just been 'forced' to buy three (I dropped a 430 which bounced very nicely... and one of my 580's keeps turning itself off every couple of minutes...)
Having been (willingly) dumbed down by my Apple operating systems, I am finding these a bit of a bastard to wing...
I will one day, many moons from now, find a couple of hours to read the manual and figure stuff out. Ohh mammy, I wish Apple made flash guns...
