So then on Verizon you could do everything but hit 'Send' on the email.

I too don't put much value on the simultaneous voice/data feature, but then again I have 2 phones, so I usually multitask by using two devices. Even without that though, I've never really felt a huge demand for the voice+data thing.

It's extremely useful when tethered. I find that I tether for hours at a time and I'm happy to be able to make/receive phone calls.

You could even hit 'Send'. The email would go out automatically at the next opportunity.
