The Surface Pro X packs a 13-inch (2880 x 1920) touchscreen, an ARM-based Microsoft SQ1 processor, 8GB of RAM and a 128GB SSD. It’s essentially a slimmer version of the Surface Pro 7 with thinner bezels and rounded corners. Microsoft also created a new pen just for the Surface Pro X. Called the Slim Pen, this $139 stylus is much thinner than the traditional Surface Pen and has two flat sides instead of a rounded body. In our Microsoft Surface Pro X review, we liked its slim, attractive chassis, bright, vivid display, and long battery life. Though we thought its performance could be better, the Surface Pro X has the best webcam we’ve ever seen on a laptop or tablet. In terms of design, the black anodized aluminum frame of the Surface Pro X has a stealthy appearance and feels great. On the back is a familiar kickstand that operates just like the one on the Surface Pro 7. At 11.3 x 8.2 x 0.3 inches and 1.7 pounds (2.4 pounds with the keyboard and stylus), the Surface Pro X is smaller but weighs the same as the Microsoft Surface Pro 7 (12.5 x 7.9 x 0.3 inches, 1.7 pounds). Apple’s iPad Pro (12.9-inch) is even sleeker, at 11 x 8.5 x 0.2 inches and just 1.4 pounds. Battery-wise, the Surface Pro X lasted 9 hours and 45 minutes on our battery test (which involves continuous web surfing over Wi-Fi at 150 nits), outlasting the Surface Pro 7 (7:30) and the category average (8:16) but powering down hours before the iPad Pro (13:14). For connectivity, the Surface Pro X features a Surface Connect port for charging and two USB-C ports.
