I don't understand how people use laptops for extended periods of time. The only comfortable way to use a laptop is with an external monitor, keyboard and mouse. The author talks about ergonomics but still uses a laptop. Laptops are for doing work on a plane or taking to a hotel room when traveling, not for being a daily driver in my book (at least not without peripherals). The keyboard on laptops is too close together, the screen is at the wrong height and angle. Trackpads are disastrous. Using a laptop for 8 hours feels like the day after running a marathon but without any of the good parts.
