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.

But I believe that inertia weighs heavily at Garmin. I asked once whether
they'd ever have the IFR-friendly flight plan entry of the 480 on the
430/530 line. I was told that they'd probably not do this as it was
considered "more difficult".

Another place where having an option (ie. waypoint entry or airway entry)
would be a Good Thing.

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?

I presume that all those little game-box things sell well more than
aviation GPS units.

Ahhh!!!! Whatever!!! The modern displays draw a fraction of the power they
did just 3 years ago and the resolution is 2 to 3 time better. Garmin is
using older cheaper displays. If they spent an extra $50-$100 per unit on
better displays of the same size power drain would be less and resolution
would be better. Don't get me started on cpu speed and flash storage very,
very, minimal costs in these units. As for the XM weather it is just a
software program on the unit and the data is available.

http://www.seattleavionics.com has XM weather requires a receiver but it
works.
