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 
out there.
