Some parts of my face, especially around my beard, were pixelated and the background was noisy. The 720p webcam on the Flex 11 performed OK in bright light, accurately reproducing my gray shirt and blue eyes. I reached 95 words per minute (short of my usual 107 wpm) with a 4 percent error rate (double my usual 2 percent error rate). The keys are made from slippery plastic, which added a few more errors than I usually get on the typing test. The keyboard is shallow at 1.1 millimeters and requires 69 grams of force to press. I wouldn't want to do my homework on the Flex 11. Despite the number, I found that with the exception of dark scenes in videos, it was still perfectly usable for simple web browsing. It's not a terribly bright display at 227 nits the average is 286 nits, while the Acer reached 235 nits. The Flex 11 has an excellent Delta-E score of 0.2 (0 is ideal), far lower than the average (2.7) and the Acer (1.5). The colors you can see are very accurate. The Flex 11 covers just 73 percent of the sRGB color gamut, falling well below the ultraportable average (98 percent) and a smidge less than the Dell (81 percent), but just above the Acer (72 percent). When I watched a trailer for Spider-Man: Homecoming, it was hard to make out the webbing on Spider-Man's suit in a scene where he stands on a roof at night, and his red-and-blue costume isn't as bright as I would expect. The 11.6-inch, 1366 x 768 touch screen on the Flex 11 is dim and not as colorful as I would like, but perfectly usable for most tasks. The right is sparser with just a lock slot, headphone jack and volume rocker. The majority of the useful ports are on the left side, including the USB Type-C port (used for charging), an HDMI output, a USB 3.0 port and an SD card slot. The Dell Chromebook 3189 is larger at 3.2 pounds and 12 x 8.2 x 0.8 inches, while the Acer Chromebook 11 N7 C731T is a lighter 2.8 pounds and 11.7 x 8.3 x 0.9 inches. Measuring 11.7 x 8.1 x 0.8 inches and 3 pounds, it's a fairly average size for an 11-inch education Chromebook. Additionally, the laptop's keyboard is water-resistant to protect against spills. It's not very high, but it's about the height of a small schoolchild attempting to hold the device in one hand. Lenovo claims the Flex can survive a 2.4-foot drop.
