So, my argument against "side by side is easier" might seem niche, but here goes:

I prefer tall-screen versus wide-screen for reading - and not just code but reading in general. The article actually hints that this is default for many people whether they realise it or not, because of newspapers and books. When was the last time you read a book with pages wider than they were tall?

On my screen, side-by-side terminals snap to 69 columns, but I can easily have 132 columns take up the whole width, and just use top-by-bottom to compare. As it is, I don't have a huge monitor, anyway, so I tend to use workspaces to give me more room, but that's neither here nor there as far as this argument goes.
