Say if I wanted to make sure my data was stored in 2 regions, and was OK with a slight increase in cost to accomplish that.
However, for my main dev computer, I would totally pay another $5USD to replicate it to another location. I don't think that needs to complicate the pricing that much. You're essentially just paying for another backup, except it's the same computer in a different location.
Another question, any plans for coming to Linux?
