What is the purpose of having the DateBook, AddressBook, ToDo and Memopad only move the map left and right? Why is there no Up/Down?
I have never used the buttons this way. The minimap is much more accurate and useful.

I'd love to see the buttons do something more useful. These could be used to center over an area like where I have my HQ, HRC and VTS. A different idea is to select a unit to follow like Andy

(Maybe a tap-n-hold with a button press could 'Set' these)
On a long screen like the T3, Sony's, or PPCs, it would be neat to have a button bar to zoom to areas.
On the square screens, there just isn't enough screen real estate. 64x64 maps take up 1/6 of the screen on my Tungsten C.
