Very smooth indeed! I hope people could add their own map repositories as in Mappero. Finnish Topo maps (NLS) would be nice with this smooth scrolling.
I did some scrolling (approx 3MB of maps loaded) and at least my N900 complained something about not enough memory (in Finnish) and become quite slow to operate.

Anyways keep up the good work!

PS: Mardy is it possible to improve map scrolling in Mappero at some point?
