the 3950 is **clearly** the best of these for gliding . .

No, the 3950 is **clearly** the best for use under office lighting,
thanks to its transflective screen. The 36xx, 37xx, and 38xx have
reflective screens, which my eyes find somewhat easier to read under
direct sunlight. The 31xx may only have a grey scale screen, but it has
better contrast in direct sunlight than any of the color models. In
reality, none of these devices can beat the contrast or clarity of the
screens on the SN10 or B2000, but they do look prettier during those
moments when you can actually distinguish the colors...

Is this because of the screens used on the SN10/B2000, or because they
are mounted on the panel and mostly out of the sun and glare?

The real answer would have to come from an LCD expert. My experience
has been that my SN10 and Palm m100 had roughly the same (good) contrast
under sunlight and shade, the Aero 15xx was slightly worse, and the iPaq
31xx had even lower contrast (but still better than any color display).

The reflective color displays work OK in sunlight, with the backlight on
or off. They work in shade if the backlight is on. The transflective
displays are basically unreadable in sunlight or shade with the
backlight off, with the backlight full on in sunlight they are
marginally readable, OK in shade.

I think the clearest indication that there is a problem with using the
39xx in soaring, is that I am always experimenting with screen
protectors to try to eliminate glare and improve contrast. I never felt
the need with earlier models...

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?

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!!

Cheers,

Yes, don't do it. They have old-style passive matrix
color displays, and
they are the worst possible choice for use outdoors.

Strange, I have been using a 2120 running Glide Navigator
II (good program, possibly clearer graphics than Win-Pilot
and a lot less colour). I bought an iPaq 5550 to improve
the display, and in daylight in the cockpit it is absolutely
no better than the 2120. Ten times the price, though.
