And frankly, I use my Nextel phone for calling and for PTT and texting, but that's it. I don't need the internet and all that jazz. I have my iPod Touch for those functions, and frankly it works well. Now that you can get free wifi pretty much anywhere you go (heck even at Wendy's!) you don't need to shell out money for a data plan.

Nextel's/Boost's iDEN network is best for PTT and voice and as someone who's had all four carriers, I like iDEN the most for voice and PTT.
