I buy it today and use few hours. I found it voice quality is quite good. My friend told me not too much noise received when he is talking to me in a quite noisy place. It sizes is incredible, light in weight. But the main weakness are the control keys. Need to side both side keys to be the directional keys to go into the menu. 
Another main function is using it as hspda modem. there should be a software provided by Toshiba makes it functioning as a HSDPA modem. Will try to look into the net and report later. Below are the photos for you guys reference.!
