However these units are quite old now and I find that even with my
current model h5550 I could happily have it's speed many fold better
.. . .
Afaicr no iPaq models have had this type of display for 2 years or
more?

The transflective

Hence we leave the backlight on (requires an efficient 5v supply
from the glider's battery) and need to solve the reflective issue.

Perhaps you could add your findings for us, to the adjacent post?

The H3950 is not a current model, but it has some advantages over
it's replacement, the H5150 (simpler design, no Bluetooth, bigger
battery, adequate audio volume). The H3950 can be updated to the
latest firmware/operating system. And it has the large display (new
iPaqs have a 15% smaller display! - the H5xxx have the larger).

Thanks for your insight . . I had not appreciated that the displays
had changed a couple of years back and become harder to use in
sunlight. So much for progress!!
