Looks like it's got good potential, but needs a lot of work before I'm likely to think about replacing Mappero with it. Two particular things I don't like: * Very heavy on battery. Using it on a six hour bike ride yesterday my battery was nearly flat at the end. * Even when in offline mode it insists on keeping asking for a network connection, presumably because it hasn't got maps at the right scale for where I am. This may be contributing to the high battery use.

@Tony: Can you give me some details how you used Marble during the ride? I guess with GPS turned on and the screen turned off? In offline mode missing tiles do not cause network queries. Losing the GPS connection however does trigger the connection dialog since we run it in agps mode which queries for a network connection when no satellites are in view.
