Take a MSI Wind U115, add a 9 cell battery, and set things up to maximize battery life and you might end up with over 25 hours of battery life. It looks like Johannes for EEE-PC.de is doing just that. He’s using the Battery Eater software to do his testing. Now keep in mind, the more you use the thing the more you’re going to chip off of that 25 hours, but I’m guessing for most folks if you could squeeze 12 or so hours out of a charge they’d be really happy.
