The most distinguishing feature of the PlayStation Vita , Sony's new portable game machine, may go unnoticed at first glance. The thing Sony is banking on occupies a tiny little area on the face of the unit, roughly a square centimeter in size. Do you see it?
Big, bright screen; Console-quality graphics; Comfortable to hold and play at length; Dual analog controls; Touch-based user interface is a winner
No internal storage; Requires expensive proprietary memory sticks (even for some cartridge games!); Only one account per system allowed; Expensive games with no cheap options (yet)
