There’s a great deal on Sony’s VAIO S Series notebooks that provides an add on battery that doubles its battery life for free. The rest of the S notebook is no slouch, either with either an Intel Core i5 or i7 CPU and a 1,920 by 1,080 resolution 15.5-inch screen with high-performance AMD Radeon graphics. It comes with high-speed USB 3.0, a back lit keyboard and a Blu-ray optical. Pricing starts at $999.
