How's the battery power?
The system will take about 3 1/2 hours to charge and then last about three to five hours on a full charge. That's with the 3D effects activated. The company guesses that people who keep the 3D turned off could get as many as eight hours. Turning off the system's wireless via a switch, lowering its brightness settings or even running it in a dimmer power-save mode will all help the machine last longer. The system charges off of a power cord or while sitting in a plugged-in "cradle."
