In stores: Sony's PlayStation Vita

UNDATED (AP) — Sony's PlayStation Vita is out in the U.S. and Europe.

A reviewer says it sets a new standard for portable games. He says more than any previous handheld, the Vita feels immediately comfortable to a gamer who's spent years with a PlayStation controller in his hands.

For the most part, the buttons are close to where they are on Sony's DualShock. The device has a 5-inch OLED (organic light-emitting diode) screen, which also serves as a touch screen.

There's also a second touch pad on the back for controlling onscreen action without blocking it with your fingers. Other features include cameras on the front and back which let you superimpose game graphics on top of real-world settings.

But the reviewer says you may not want to use the cameras to take photos. He found the results unacceptably grainy.
