One more consideration: your subject line refers to "Compaq
Aero." If,
by that, you mean the older Compaq 1520/1530/1550 series that a
lot of
us still use, then I'm not sure that WinPilot or SeeYou Mobile
will
run satisfactorily (older, slower processors; monochrome
displays).


Many have noted here that your display may work better in
sunlight than any of the more recent colour displays, which can
often be difficult to read in flight. However, if you needed more
cpu speed and bought a new gadget chances are that you could turn
off some of the clutter and increase font size (thus making it
easier to read) with an arguably better overall result.
