Latitude series. It used to be available in D630. Now there are no new products in the Latitude series. I used the blue finger sleeve before, which is better than thinkPAD's. Latitude series is a main commercial machine specially built by Dell. All three-year warranty.
Not seen by other brands. Just looking at it,
Dell's current Latitude 6430U E6330 E6430S E6530 and.
