I just discovered that the PapeWhite doesn't have a hyphenation algorithm and not only defaults to full justification, but has no ragged right option! Now that, in a modern eReader, is simply inexcusable.

Can any of this be changed via jailbreak and hacks? I wasn't anticipating jailbreaking this device, but it looks like there's no other way to make it a decent eReader (assuming there is a hack to fix this).
