I don't have a Kindle, but I have an Acer Iconia (like an Ipad) downloaded a pile of books to it from all different sites. I can use the Kobo app, the Dymocks app, the Amazon app etc etc etc. Acer has all the other "fun" benefits too like being able to play games, listen to music, watch movies etc when you are sick of reading.

I use it mainly to read though, in bed. Handy when you are sick although the other day I put two movies from my computer onto my USB and then plugged the USB into the Acer and watched them in bed. The screen brightness is adjustable, so you can adjust it so it is comfortable for your eyes and you can read in the day or in the night You can also toggle it so it is a black page with white writing, but that is a bit hard on the eyes.

I don't think I could ever go back to a real book again.
