It's probably the added height creating a more comfortable experience, but as somebody who enjoys the 'bookish' appearance, I actually like the margins which are there.
For my tastes those margins are way too wide for a small screen, though okay on a larger screen. Decreasing them would allow another word or two per line on average.
