Honestly? Gravity, mostly. Also the fact that my laptop doesn't have a ceiling mount and I'm not about to spend $500 on a standing desk just to flip it upside down. But hey, if lying on your bed staring up at a monitor suspended in mid-air helps you debug that segfault, who am I to judge? Someone really looked at their ergonomic nightmare of a setup and thought "you know what would make this worse? Fighting gravity while typing." Props for the dedication to maximum discomfort though. Your chiropractor is gonna buy a yacht with your money. The real question: how many times did they accidentally knock that laptop off before getting the angle just right? And more importantly, what happens when you need to reach for your coffee?
