Ok, so i have a dr480h and love it. a few complaints -
one, it's heavy. don't like heavy.
two, you can't do anything with it whilst it's on the recharge stand
three, can't edit it whilst it's playing or recording unless you pause the track
other than that, i love the sound quality and i think that it's sexy.
how much better/different are the other models? I've heard bad things about the n10 battery situation, although i love that it's light.
dr420h looks good, but can't tell the difference really!
hope you can help!
