Two reasons... reliability and serviceability.
Most of the components in these systems aren't COTS (commercial off-the-shelf) items. There are many custom-made parts involved here that have long been discontinued and in the case of some custom silicon simply can't be replaced with something else. So, once you're out of spares, you're done. There are some partial upgrade paths, at least in the SmartNet/SmartZone world, to let you upgrade the hardware and later reflash the software to move to P25 trunking, keeping your existing transmission lines and antennas.
Also, at a certain point, you end up wasting more money and aggravating, if not endangering, your end users by fixing things that should have been replaced years ago. I could have crates of spare MTS2000 radios for parts, but if your radio only works for three weeks at a time and then you have to turn it in during the middle of your shift for service, is that the level of service you expect? (I'd hope not!)
It frustrates me the mentality that comes along with radios in public safety. Agencies don't hesitate to spend money on new computers, new cars, new guns, but radios they expect to get at LEAST 15 years out of. I don't get it.
Ultimately it all comes down to money, and money goes hand in hand with politics.
Oh, and even the new APX line from Motorola does support Type II trunking. No Type I but that stuff is archaic at this point. ASTRO 25 line didn't support Type I either.
