I'm not getting the N810, because
a) I'm no good with reduced-sized keyboards with too few keys, and
b) I prefer a full-size BT foldable keyboard for those occasions where the on-screen isn't good enough, and
c) I have a small BT GPS already, and
d) I can always buy Navicore separately if I need it, and
e) I really really need continued access to two full-sized SD slots.
As the keyboard, maps/navi, gps also add considerably to the cost with for me not-needed functionality, it's pretty obvious that the N810 is not a good match for me. For some people it will be the other way around.
