No 3G, more tablet.
I'd prefer "no" to these.
More efficient Bluetooth so you can connect to your phone (on contract), replace that phone and still keep the internet thingy (as opposed to having to get rid of both).
More ruggedness, more resistance to water.
Better screen (daylight readability improvements, slight increase in size to A6/6x4).
Longer battery life.
Take what the n8xx series gave us and make them more that.
Not as sexy as 3G, but a damn sight more useful.
