You're not viewing the whole picture. Simultaneous phone and data is very important with this kind of phone. I frequently stream music or run one of the streaming scanner applications to my car stereo via Bluetooth while driving. If you're using an app that is constantly streaming data you're going to run into an issue with data streaming and phone calls.
if you get a call while using data, the data stream is interrupted by the call. Verizon's system was not engineered by morons. This is just like the talk and text person above.
