that first picture is an extremely good illustrative demonstration on what laptop/notebook users do much more often, than desktop computer users, just because they have wider choice.
computer users are fond of runining the health of their own body with insane body positions, and keeping those positions for insanely long time. and the number of insane positions body positions is multiplied when using a notebook.
anyhow. computers, data, result of our own work are precious, so is our time that is lost without work just because of a computer failure. so anyone is right when suggesting not to waterfall, cook, grease, the computer. but keyboards are not precious. so if you cumulate the time that is spent by turning away from your computer desk in order just not to spill coke onto the keyboard ..... maybe two keyboards per year are cheaper.
