Keyboard: usually the one that is part of a laptop. Some laptop keyboards need some time to get used to, but that's fine. Backlight is appreciated. No mouse, no trackpad, I live by using a trackball. Best is the Logitech Trackball M570, good alternative is the Logitech Trackman Marble. I like to use different trackballs, but somehow other brand trackballs are always disappointing and often less durable as well.
