Dell Latitude E6430s vs Latitude E6430u: classic vs Ultrabook
 

The Dell Latitude E6430s and 6430u are great examples of the evolution of laptops. The E6430s is the classic notebook that we've seen for a long time, with docking port, standard DVD burner and a 2.5-inch hard disk. The 6430u is a more current design. Sleek, no DVD burner, and no room for a 2.5-inch hard disk and instead an mSATA SSD. That also makes it a fast machine.
