If there's more than a little visible desktop around my terminal, I feel like I'm working through a keyhole. Also, being able to stretch out horizontally to 160 characters or more is wonderfully relaxing; it makes chaining two or three tests in an IF readable, in the process saving at least two lines of vertical space, which is in far shorter supply on modern 16:9 displays. (Although, it seems you use your iPad in portrait orientation, which reverses these benefits, I suppose).
