The Sony E Series 15.5" Laptops is a class in itself as a laptop, it has diamond-shaped patterns for its outer design that is "fingerprint-proof" and more features that one can imagine.
For the 15.5-inch E Series Laptops,
there are also two different variants for this model, one is the customize-to-order (CTO) model and one preconfigured model assembled by Sony with specifications to give the buyer value for his money.
Similar to its 14-inch sister, hardware

Pentium B950 (2.10GHz) up to Core i5-2430M (2.40GHz / 3.00GHz with Turbo Boost Technology). Onboard memory available is 4GB, 6GB, or 8GB DDR3-SDRAM-1333 with either Genuine Windows 7 Home Premium or

410M with up to 1GB available VRAM for crystal clear picture quality. You may choose your size of hard drive space as well be it as low as 320GB (5400rpm) or as big as 750GB for all those movie files that you want to bring along.
