Yes, and I never said that.  We are talking about Ham 
Radio, and in that hobby, to me, the Kenwood is not
obsolete until there is another HAM radio to replace it.

Yep, and I'd say that the fact that 28% of all APRS users
have one actually on the air speaks highly of their not
being obsolete.  And the fact that 85% of all APRS
users that view APRS while mobile use them also speaks
to their continued utility.

But this is Ham radio.  And although Japan has an
amateur radio population that is over 3 times the
size of the USA, it sill only has NAVITRA in the
HAM market (though they did upgrade to APRS
a few years ago).

Sorry, but HAM radio and APRS is never going to keep
up with what the $100 billion phone industry can do
with their resources and market.  If you expect that,
then I fear you are always going to be disappointed.

Yes, the cell phone industry has passed us in the
last 20 years.  But the one thing we have is a common
shared channel that always works at the local tactical
level anywhere on earth.   We need to focus on what
we ham radio first responders can do better with that
than any cell phoone junkie who shows up with all his
toys and no connectivity.  (cant talk to they guy
1 mile away)...

But they still work fine.  And don't run on Iraq oil.
Some people (though rare) prefer them by far.

What else do you think we can do on a shared
1200 baud channel with a few other hams that
show up with APRS at a ham radio support event?

Tell me what is new and better that cant be done
within the spec and be backwards compatible?  If
you just tell me what these "new and better" things
are, then lets see if we can do them...
