Hello, I have Dell Latitude 11 5179 m5/8gb/256gb/slim keyboard, and I'm not happy with it. Because of the slim keybord, the computer's dimensions are murch larger. It's very inconvenient to travel!!! And the Dell's fingerprint does not work well, I do not use it. I advise you to buy Dell Latitude 11 5175 m5/8gb/256gb ONLY with the optional Latitude 11 Keyboard. It will be slightly heavier, but you can work for about 9 hours without additional battery charging, because there is one more battery in the keyboard. With best regards Alex.
