I just picked up a Dell Inspiron 13. Purchased it from BestBuy online. Out of the box it looks pretty impressive. The battery is pretty big and kind of sticks out more than I would have expected. Perhaps this is what gives it the longer battery life.
The screen is almost a little too small, but going from a 14 to 13.3 I think I would rather have the smaller size. It does feel a little lighter than the Latitude D610 I am replacing.
