My computing devices are: an iphone (4s), an ipad (air 2), and a windows computer with a 27" monitor. I also have a kindle, but that's not general purpose. I could probably replace the computer and ipad with a macbook, but 1) it would cost more money and 2) wouldn't be as mobile and easy to use as the ipad (for surfing in bed / on the couch, watching movies while eating, listening to music) or as usable as the windows computer (for coding and playing games) because of the smaller screen size and the relatively crappy keyboard / mouse. I could remedy the latter limitations with a docking station, separate monitor and keyboard, but now the solution is not just more expensive but much more expensive and even more cumbersome as compared to the ipad.
