It's VERY prevelent.
It's not a matter of whether it's "that good". Rather, it a case of
"it's the ONLY device that meets the requirements".
Until this year, NO other TNC could implement a stand-alone (no computer
required) WIDEn-N digipeater out of the box. [NO other TNC, other
than Kantronics other more expensive models, ever offered N-N
digipeating capability, including callsign substitution and dupe
detection/supression straight out of the box.] No other device
consumes as little power (less than 10mA), or was as flexible (it can do
data telemetry, act as a digipeater, act as a dumb tracker, and can
combine RX data and GPS data into a single serial port when used with a
computer) as a KPC3+ .
A TNC2 made into a smart digi via UIdigi firmware consumes almost 30
times the power (300mA), a real issue for remote solar-powered digis or
emergency power backup scenarios.
As of this year, the TNC-X with it's X-Digi piggyback board, and the AGW
microTNC, can also implement stand-alone n-N digipeaters, but the KPC3+
has been doing this for over 8 years.

No. It's more like the "tyranny of the installed base" problem that
plagues software developers that have to maintain compatibility with
previous versions of programs or operating systems because so many are
