Refresh rate relates directly to power. Ideally, the box would offer
options (ie. rapid refresh, more power consumption vs. slow refresh,
longer battery life). That may be a "didn't think of it", I suppose, but
I'd be surprised since this is standard in laptops.

What's especially sad is that every, single one of the "way cool"
aviation features of the 496 are impacted by this problem. Here's how
it goes:

1. You're cruising along on a 100 mile x-country flight. This is
typical for us.

2. You've got the screen zoomed into the 30 mile range, so that you
can see any details at all (like towers) on the little screen.

3. You want to check the runways at your destination airport, which is
NOT displayed. (Remember, you're zoomed in so that you can see stuff.)
The 496 has the runways stored in its database -- all you have to do
is put your cursor on the desired airport and hit "enter" to see them
all.

4. In order to click on the desired airport, you must "slew" the
cursor off the edge of the screen in order to find it. This means
hold the arrow button down, slew to the edge of the screen -- wait
three seconds while the screen disappears and reappears -- and
continue.

The REALLY bad thing is that the cursor doesn't stop moving when the
screen disappears, so that in those three seconds you can easily WAY
over-shoot your target airport. (I've even ended up in a different
state during the time it's blank.)

5. Repeat ad nauseum.

This process must be performed in order to see ANY of the good stuff,
including accessing the AOPA restaurant/hotel guide, radio
frequencies, field elevation, airport diagrams, METAR and TAF weather
-- you name it, you've got to put your cursor on the airport and push
"enter" to activate it -- which means slewing.

My son just laughed when he first used it...until I told him it cost
$3,000.00.

Then he just laughed at *me*... (Until he figured out that it had come
from his future inheritance...)

;-)

Still, I'm suspicious that none of the other vendors have leaped past
Garmin. That suggests that there's a part of this equation I'm missing.
Perhaps the development costs to "get it completely right" would render
the unit too expensive given the small audience?

Yep, me too. Lowrance -- the world leader in nautical GPS -- has been
"promising" weather for over two years -- and STILL nothing. It must
be a lot harder than we think it is...
