I for one can agree to both sides of the Nextel issue. I hate their voice and data coverage, probably the worst I have experienced in my area. But, even with other companies having PTT on devices, my last test with ATT PTT was around a 30 second delay, opposed to ~1sec. Say working on a construction site with a crane, spotter needs instant communication with the operator (and their company gave them phones instead of walkie-talkies), they would need the instant PTT. Yes, their CS is horrible, but when you look closely, they all are. I will say that they have been the BEST at giving up monitary credit to apologize for inconveniences, opposed to offering "bonus" minutes. I have my plan set to the minutes I need, I dont want more for free. Its been rumored for years now that iDEN will be dead by (whenever) and has yet to happen. If they can release a better selection of phones/devices I see a chance for revival.
