The last 2 books I've read (the hunger games ones) were all bought and read on my 2 android devices (Galaxy Nexus and SIMless HTC Nexus). Cross-sync is awesome. I read on planes and before sleeping (you can invert the colors to have black background) The worst part is that I have an actual Kindle (albeit old)... somewhere. I don't miss it. At all. I love reading the kindle app on the phone anywhere, even buying the next one on the spot.
