Backpacking Around the World. Which camera would you take?

Limiting myself to the cameras listed, could you afford the RX1 and RX100? This would give you the highest quality (RX1), flexibility (RX100), an excellent backup camera, and I think take up less space that the OMD kit. If you can't or don't want to get both of these, I'd recommend the OMD instead, as neither Sony strikes me as flexible enough to cover all your needs.

What are you doing for picture storage along the way?
