yeah that's not a big deal to you. but a lot of people are on a call and have to look something up at the same time. i receive my texts through data on google voice. when i'm on a phone call it notifies me like a regular text through push. that wouldn't happen on verizon.
just bc YOU don't use it doesn't mean someone else doesn't.
If you polled all 92 million VZW subscribers and asked them how they feel about not being able to recieve data and voice at the same time, the response would probably be: "What?"
The vast majority of people have no idea. Those that do, great, give up being able to actually make a call so that you can browse the web while on one...until it drops.
There is a reason the VZ iPhone has been such a hot topic. It isn't because AT&T has such a great network and we all just want to be a big happy family. It is because a significant portion of AT&T subscribers are unhappy with their ability to use the iPhone as a "Phone".
