The kindle has only two things that make it competitive enough to be worthy of discussion- e-ink and lighter weight. In every other category (ok, excluding price) it fails compared to the iPad.
on e-ink there isn't really an advantage to my eyes. I've never gotten eyestrain reading on my (first generation) iPad. The image quality of the e-ink display is worse than even the first generation iPad (to my eyes), in large part because the e-ink display is not responsive.
weight- I deal with it on the iPad. The kindle is better in this regard, but not enough to make it compelling.
Amazon had a great product in the original kindle, but it was a single purpose product. It hasn't kept up (or e-ink hasn't advanced fast enough) and its losing the race.
