"With a bluetooth headset, and voice dialing, does size really matter? As long as you can figure out how to carry it, that is."
i personally don't like wireless headphones or headsets, i listen music alot and this is a issue for me
also since i use it for music, the size is important because change songs in the device must remain simple and a big device makes things a bit complicated
voice dialing, well, i tried those features in the past and couldn't do much with it, perhaps try with it again?
yes, carry it is what matters now, if you can do it easily or not and how you use it
