Very nicely done, very informative. After trying out the Kobo readers in my local bookstore, I'd add there is one big difference not mentioned here, Kobo's left-aligned text option, which the Kindle and the Nook still lack. I have both a Nook and a Kindle, and discovered the ugly and inconsistent gaps in word spacing are visually awkward and affect readability (I always rotate the Kindle horizontally, and make the lines longer, to get fewer big, ugly gaps) See comparisons here to understand why it matters: Because the Kindle or Nook have yet to wise up and give us a left-justified text option (even though the comment boards are full of pleas to do so), or at least hyphenated text, the Kobo reader is looking like a pretty good alternative.
