Acer Chromebook 315 vs Acer Chromebook 311

Buy the Chromebook 315 if you want a big 1080p touchscreen and a number pad for spreadsheets and long typing sessions. Buy the Chromebook 311 if portability matters more than screen size. Both run the same Celeron N4500 and 4 GB of RAM, so everyday Chrome OS speed is similar. The 315 has the better screen and more ports; the 311 is lighter and easier to carry.

• Choose the Acer Chromebook 315 if you want a 15.6-inch 1080p touchscreen, a dedicated number pad and a bigger chassis for desk work.
• Choose the Acer Chromebook 311 if you need a small, light laptop for class, travel or a bag, and an 11.6-inch screen is enough.
