MSI's never been a slouch when it comes to its Wind series, but this new U115 seems to be something else entirely. In tests done by the folks at Eee-PC.de, the laptop ranged from 5.5 hours to 15 hours of battery life, based on level of usage. Even 5.5 hours is good for continuous use, but we could imagine all sorts of happiness with 15 hours of battery -- like camping. The laptop gets some of its battery mojo from its hybrid storage system, which allows the laptop to run entirely off of its 8GB of SSD memory, with the 160GB hard drive spun down to save power. The SSD is user-replaceable, if you don't mind a little warranty voiding, and the folks at nvision have thrown caution to the wind in ripping apart their U115 for our viewing pleasure.
