Lisa Gade reviews the slim and light Lenovo Yoga C630, a 13.3” Windows 10 convertible Ultrabook running on an ARM processor- specifically the new Qualcomm Snapdragon 850. It offers very long battery life and a fast 4G LTE wireless connection in addition to the usual WiFi. The Yoga C630 (not to be confused with their similarly named Chromebook) is available with 4 or 8GB RAM and your choice of a 128 or 256GB SSD. The laptop has a pleasing (though very glossy) full HD display supporting touch and optional pen. A fingerprint scanner, backlit keyboard and Microsoft Precision trackpad are standard.
