I think it would b better if it was on the left hand side.. and the usb charger should have been on the right hand side..... anyone, except me, finds this annoying??
let me explain,

u have ur phone in ur pocket, listening to music via headphones... the phone is upside down in ur pocket.. u receive a call - u have to turn the phone the other way to talk... ....
ok, u will talk via headphones probably, but u still have to turn it to see who is calling or to answer/decline the call....

secondly, ur phone is on charge (most of the time it normally is) and u receive a call... Its definitely not a good idea to take it off charge, it might break the connector as its hard.. so, I leave it on charge and take the call... the charger is ON TOP hanging ...
