I have been using a HP IPAQ "Travel Companion" which I think is the
5150 although this does not appear on the unit, neither in the manual.
The display is similar to the 3850 series which means poor in bright

I do not think so. The only "Travel companion" I know of that is a PDA
(not the newest one 310 which is not) uses display that is very
different from 3850. It is a transmissive display (not reflective)
backlit with LEDs and is totally invisible in strong sunlight. On the
other hand 3850 is a fully reflective display and is quite good in
sunlight
