I have a Kindle and I took it on our Carnival Cruise with us. Saw lots of folks on board with one as well, sitting out in the sun reading. They are absolutely wonderful for outside time, it is like reading a regular page with no glare. I've gotten lots of free books as well as cookbooks and a few games on mine. I've purchased 2 games for mine for waiting rooms and such. The charge lasts a super long time. We were on the cruise for 5 days plus travel back and forth to the port and I never even brought the charger with me. I charge mine about once a month or so. LOVE IT! ! !
