Some other things to consider.

1.
A better screen with 8 bits resolution and better color fidelity.

2.
LED technology possibly.

3.
Battery technology improvements. No matter what Nokia does with power management it would be nice to know that we have best in class battery performance. That seems to be very much a moving target at the moment.

4.
Solid provision for a lanyard / locking loop!


These are just a few more ideas. Not to confuse people but I would like a device that does multiple things well. A device that supports me at work, a device that allows remote internet access and a device that support hobbies such a photography. Maybe to much to ask of one device, at least with current technology.
