Hi Mike, I appreciate the reasons for Seeing Eye having server-based maps only at this time. I hope for some sort of hybrid solution in the future, which could retain the advantages of maps being updated more frequently, as they are updated on the server, but still allow us to download map segments if we need them, e.g. when we know we're going to be in bad coverage areas or if we anticipate heavy use of the app. I've been using the app, and I haven't noticed that it eats battery to the extent that I would be worried about running out of power for phone calls. However, I do have one of those cases with an auxiliary battery pack, which has come in handy on occasion. Given how my Android device eats battery when the screen is on, even when not running a gps app, I'm happy with the battery results on my 4S, but would like to see the added flexibility that is apparently possible with something like Google Maps, at some time in the future.
