MSI Wind U115 rated at 15 hours of battery life

From Engadget -

In tests done by Eee-PC.de, MSI's new U115 established some sort of new standards by ranging from 5.5 hours to 15 hours of battery life. Even 5.5 hours is excellent for continuous use. The extended life is made possible by the netbook's hybrid storage system, which allows it to run entirely off of its 8GB of SSD memory, with the 160GB hard drive spun down to save power.
