Interesting question. I really should have worked that out already :) The current plan involves being in about 20 countries over the course of just under 3 months. So let's say 90 days x 50-100 photos per day x 2-3MB per picture. That gives somewhere in the region of 16GB right there; with backup, twice that. And that's probably on the low side. Hmmm. I'm going to need more space (and more upload bandwidth) than I thought!
