I've been using this phone for about 4 weeks now. I have used Nextel in the past and the new Sprint Ready Link PTT capabilities are nearly equal to the Direct Connect feature from Nextel.What I like about this phone:-compact size-camera that takes &quot;ok&quot; still and moving pictures-easy upload of pictures to web-downloadable ringtones-PTT-reception is very goodWhat I don't like about this phone:-The PTT is not error correcting. What that means is that since the PTT from Sprint is essentially VOIP (voice over Internet) -- if your phone can't connect to the Internet is stops with this honking error message. Rather than retry it sits there waiting for you to press a key to acknowledge the error. This unfortunately disqualifies the phone for serious use by many companies.-Battery life seems very short. I believe this is because of the Ready Link constantly communicating with the Internet. I'm getting maybe a day of medium use.-The ReadyLink tones sound like something that should be on a Barbie walkie talkie for kids. Believe me half the time you'll never hear the. Oh - and they need an alert feature too.
