I’ve got T-Mobile GPRS service which lets me obtain a data connection while on the go via Palm or laptop, like now as I head back to NYC on Amtrak. As I surf, blog and email on the train, I can also make calls which politely holds my data connection (or at least slows it down) and then picks right back up when you end your voice session. This is not only cool, but amazing… I guess I had noticed it while on the Palm previously, but had not really appreciated how slick that is.
I imagine a faster connection might not have to pause as there would be enough juice to let it all through…
