The Aspire Timeline notebooks manage to get 8-10 hours of battery life and they start at just $699. It accomplishes this through Intel’s ultra-low voltage processors, LED-backlit screens and dual graphics cards. Apparently you’ll get 8 hours with a regular hard drive, and 10 with an SSD.
The charger helps keep the power consumption down by cutting the power when it senses a full charge. The notebook is a tad over an inch thick, by 13.3, 14 and 15.6 inches at 3.5-5.3 pounds.
