Battery LongRun or Sprint
The BatteryMark runs with a very high CPU load. Transmeta's LongRun technology insures that applications requireing CPU power are not throttled by the power management.
When you compare the power needed for this battery time, the Transmeta design looks much better. The LongRun application reduces the power consumption of the Transmeta CPU considerably.
When playing MPEG4 movies, the LongRun Economy mode kicks in and keeps the system alive.
