Amazon published this Kindle Fire vs. iPad 2 page shortly after its announcement on September 28, 2011. I thought it was just a temporary promo, but it turns out that Amazon is still pushing it heavily.
Marco has put together a dead set brilliant feature-comparison checklist which gives a much truer picture of how the Kindle Fire lines up against the iPad 2.
FWIW I really love my Kindle Keyboard and think that it has the better reading experience when compared to the iPad 2, however for EVERYTHING else the iPad 2 wins hands down. No competition.
