The Book 9 Plus looks almost identical to the older Book 9, and that’s a good thing. This all-aluminum notebook has refined, subtle curves, and at 3.2 pounds and 12.6 x 8.8 x 0.54 inches, is fairly light. Its 3200 x 1800-pixel, 13.3-inch touchscreen is gorgeous to look at. The notebook is powered by a 1.6-GHz Intel Core i5-4200U CPU with 4GB of RAM and a 128GB SSD. Samsung includes some helpful apps such as Side Sync, which lets you connect and interact with your Android phone on the notebook. At $1,399, the 9 Plus is pricey, but the 8 hours of endurance makes it worth the expense.
