MSI Wind 9-Cell Battery Available from Lion Battery
Now that the MSI Wind is going to be available at Best Buy, but at the moment with only a 3-Cell option, you might be looking for some extra juice. It turns out that Lion Battery has a Mugen 9-Cell option for sale if you are willing to go the third-party route. It will set you back $180 (ouch) and it weighs in at one pound, but if you are looking for six extra hours it might be worth a look.
There’s also a code (MSIWIND.NET) that will save you an additional $20 on check out.
