I have one criticism... it really eats up the battery even if you just leave it open in the background...is this because it's constantly looking for a GPS fix?
I've been having problems with it today actually...possibly related to upgrading to PR1.3 last night? It keeps telling me it can't guess my location, and asks me to choose one from "the list", then I get an empty field, where I've tried typing in 'London' for example, but nothing happens...can't get it to work at all.
