For the personal life and many forms of work, PTT does not make sense.
But for the construction and IT support on a large campus (I work for a city, so my 'campus' is city wide), PTT is golden. Start working on a computer problem in one server room while another person is on a desktop 2 miles away: CHIRP: "okay, try setting the network to at XYZ setting." 3 mins later, CHIRP: "done, can U see the server now?", "Nope, try ABC at a slower speed", 4 minutes later, CHIRP: "Got acces, thanks, clear". Maybe a minute of PTT time over 30 realtime. Just enough communications but not too much...
Nice extra to a phone for the family life if there is not much extra cost, but I think not a "Killer service".
