Good point. But Sprint is going to lose a lot of customers anyway as soon as they kick them off of Nextel iDEN, because anyone who is still with Nextel is ONLY there for the iDEN PTT performance, which is still awesome and still untouched by any other company or technology.

Almost every single Nextel customer despises what Sprint did to Nextel, and the poor customer service Sprint provides compared to the great CS they experienced with the original Nextel, so as soon as the Nextel iDEN PTT system is not available to them, they'll mostly leave Sprint altogether.

Another thing to remember is that only iDEN is a true "peer-to-peer" radio dispatch system that does not rely at all on the PSTN (public switched telephone network). Nextel Direct Connect goes tower-to-tower via T1 lines, completely bypassing the PSTN that all current cellular systems use. That is the reason why Nextel Direct Connect PTT frequently stays up & running & is so much more responsive even when everyone else's cellular service (ATT, VZ, Sprint CDMA, T-Mo) goes down in regional emergencies, because they are so overwhelmed that they bring down the PSTN, thus breaking their vital link so they just don't work. Nextel Direct Connect bypasses all that and keeps on working (as long as there is electricity getting to the towers and the Internet is still functional, which so far has usually been the case).

All of these new whizbang PTT systems are emulators running on VoIP, which can work decently as long as the systems their VoIP is running on are not overwhelmed with traffic and as long as the PSTN is not down or itself too overwhelmed. Yes, the promised new PTT systems offer other benefits that iDEN can't deliver (i.e. high-speed data), but not a single one of them will be as fast, nor as reliable, as the original Nextel iDEN Direct Connect dispatch system.

So all of you that are dancing around the campfire and high-fiving yourselves in anticipation of this supposedly great new CDMA-based PTT that Sprint is going to introduce in Q4, just remember that two very important operating characteristics will be forever gone when iDEN is decomissioned: (1) iDEN's stellar PTT performance, and (2) iDEN's stellar PTT reliability.
