Is digital two-way radio obsolete?

In 2007, Motorola launched their new MotoTRBO digital two-way radios. At their heart, they use the DMR digital radio open standard, which has become the industry standard for commercial digital two-way radio. Since then, digital radios offer more features, better audio quality across the coverage area (but worse audio compared to a good analogue signal), and can do things such as telemetry, messaging, GPS, etc. better and more easily than an analogue radio could.
But what if you need to do more with your radio? What if you could use it for job dispatch, indoor tracking and navigation, email, time recording, picture messaging, displaying location and navigating to a certain colleague, and more? What if you could upgrade to keep up with technology and make changes or turn on features at any time for no extra cost?
Smartphones are essentially tiny computers in your pocket. With the right phone, a remote speaker microphone, and the right software, they can do everything a radio can do plus more. We call this PTT (Push-to-talk) over cellular or PoC. Instant and reliable group or 1-1 calls? Easy. Location services? Naturally. Mission-critical reliability? Telstra LANES, private LTE or properly built wifi mesh. Ruggedness for LNG/mining/oil and gas industries? Of course. Cheap accessories? Lots. Long warranty? Up to three years.
The choice in Android smartphones for business use is mind-boggling. There is a device to suit every need. An Android device is essentially a small computer that can do everything a two-way radio can but without limitations. In this respect, digital two-way radio has already been superseded.
