Aw. I can't believe he didn't explicitly mention the e-ink used by the Kindle.
It really, really makes a difference.
There are a million annoying, awkward things about the Kindle. But they're all worth it just due to how dang readable it is. I can use an LCD all day long (and do). But for reading documents/books of some length, linearly, for long periods of time, e-ink is really nice.<p>(I'm sure i'll eventually have an iPad, or something like it, i just don't compare it to a Kindle.)
