ViewSonic’s 13.3-inch ViewBook Pro (VNB131) promises up to 8-hour battery life with the standard 6-cell battery but you can also swap out the built-in optical drive with an included 3-cell battery slice for an extra four hours of juice. That’s a nice touch for anyone who’s on the go a lot but still needs to be able to work with disc-based media from time to time.
The notebook’s specs include the following:
- Ultra low voltage SU7300 Intel Core 2 Duo CPU
- Windows 7 Home Premium
- 13.3-inch LED-backlit screen at 1280×800 resolution
- 320GB hard drive
- 2GB RAM
- Removable DVD burner that can be replaced with an included 3-cell battery
- Two USB ports, card reader, HDMI/VGA output, 1.3-megapixel webcam
- Aluminum enclosure measures an inch thick, body weight of 3.61 pounds
It’s available now for $949 from ViewSonic.
