This keyboard teaser shot for the Vaio Pocket, Sony's upcoming mystery netbook, shows two things. It has a full size keyboard (like the Vaio TZ) and a track stick for mousing.
I dont know about the fullsized keyboard thing. the spacebar seems a bit short in comparison to the rest of the keys, so does the shift key (or whatever the larger key is) in the first picture. I think this is going to be a slightly undersized keyboard.
