I don;t like sony DC. in my opinion, nikon, olympus, canon are better than sony. Sony Dc only has a good looking.
And I think olympus d-550 and nikon coolpix 2500 are better than sony P51.

USB is USB. I won't talk about USB 2.0 becasue you must be confused. I just say that for USB no diference between notebook and desktop.
