GPS - I wouldn't buy without it. It's just too useful for navigation.
3 axis magnetometer - from recent experience it is sometimes very useful to
know which way you're facing as well as where you are. 3 axis accel, gyro and
a pressure sensor would be nice but less important.
Daylight readable screen - again from recent experience in a sunny
environment. A transreflective screen, or one from PixelQi, would be better as
they would cut down on the power needed for backlighting in bright
environments. An ambient light sensor would be good to automate the backlight
level.
Better screen resolution - at least 640x480. It really does make the screen
more legible, and significantly broadens the number of apps that can be used
without gui porting.
USB host mode
Standard connectors for USB host/otg/device and charging. These could be in
place of the mini-HDMI and coax power connectors.
Given what's on the 40 pin connector an option might be to have a dockable
module that can go either on the end of the MiniBook or inside the SmartBook.
That would enable everything but the screen changes without changing the
existing MiniBook design, and seems similar to the DualScreen module in design
philosophy.

If debian can run on it there should be no problem porting to other distros.
Similarities to the beagleboard and n900 may mean other distros can already
work with it.

That probably depends on what they decide to do. On the hardware side they
should be more than capable of implementing anything suggested above. Pick the
right components and support may already be present either in the mainstream
kernel or other open drivers. See the FR Navigation Board[1] for some
examples, and n900 sensor support in the mainstream kernel for others.
