Does anyone know whether the LCD display for this unit is
transflective or transmissive?

John,

Sunlight readabiltiy of a display does not have that much to do with
Transflective or Transmissive.

The key items a

Touchscreen *- extremely bad for *sunlight readabiltiy *produces
glare *you can see this on most PDA and or phones. *To see the
displays better you have to tilt them to get the correct light on the
screen.
Coatings on the Screen - coatings depending on the type significantly
reduce sunlight glare. * 2 different coatings *are required to have
good sunlight readability.
Contrast ratio - 11 to 1
Brightness - 1000 -1800 nits (cd/m2) *this backlight will produce a
very readable screen.

Richard, *I like SeeYou Mobile and I like much about the Ultimate so
if it was smaller, cheaper and I lived in the US I would probably buy
one.

Why I asked the original question is that most references to the Ipaq
31* series that I have read describe the display as "transmissive"
although there are some that describe it as transflective which is how
the 4700 display is always described. *I own both types and the
displays are clearly different in natu

The 4700 display shows up (rather dimly because the observer's pupils
are shut down) under direct sunlight and it makes virtually no
difference whether the backlight is on or off. *It clearly works in a
reflective way. *With the 310 the backlight must be on maximum to be
visible at all with the sun on the screen - and reflections mean that
the screen is unuseable in that scenario. (Fortunately it is easy to
angle the 310 in flight so that condition is rare)

On the other hand the 4700 has poorer full backlight brightness than
the 310 series and the latter has better visibility in indirect bright
sunlight.

The AV80R is just about affordable, a familiar size, seems to be
brighter than both of the above, runs SYM, *and has the right
connectors for integrateing with glider instruments so if it has a
transflective screen (as seems likely) then I think it might be worth
considering. *Pity about the low resolution however.
