Could be, and it wouldn't be the first time...

The dual-use TNC is good news, as is the flash upgrade path.  Haven't
seen either advertised (or tested, for that matter).

I'm not sure what planet or hallucinogenic pharmaceuticals one would
have to be on to consider this an _improvement_.

To me, that's more feature creep than actual improvement.  I'm gonna
buy a $600 radio, and not use the radio part of it?  I don't think
so...

This would be interesting if it were available for a reasonable price
without the radio - again, I'm not gonna spend $600 on a radio and not
use the radio part, and given the obscene cost of a D700 control head
replacement, I don't see it being offered separately at a reasonable
price.

If it speaks NMEA, how does it do that? What you really mean is that
it puts out a custom waypoint symbol that only one rather expensive
GPS unit will understand, right?  If it doesn't work with my MAP60C
(or insert your favorite GPS here), that's a pretty limited feature.

$600 for a D710 weather station, or about $150 for an Opentracker and
any old radio weather station.  Next!

The sorting/filtering is nice.

Did they fix the item display bug?

Did they add some RAM to make it useful for higher bandwidth packet
applications?

I don't want folks to think I'm down on Kenwood, or that I am
recommending they not buy the 710.  I have a 700, and a D7, and I like
'em both. I am a little disappointed that there weren't many real
improvements, especially after the years that separated the D700 and
D710 releases.

I do object to noting every _change_ in the radio and calling it an
_improvement_.  Let's be honest in our assessment of the device, and
not just be unthinking Kenwood cheerleaders because they're making the
only ARPS radio.
