Tablet not an E-reader?
You do realized that your 'bona fide' Kindle is a tablet, right?
But the ONLY bona fide e-reader? Really? Does that mean that the Kindle app doesn't exist? Or Lumiread? or other e-readers? I got my android tablet specifically for E-reading as I can adjust the font size so I don't have to squint, for astronomy, and to preview photographs while on site. I also use it for road trips, as the Google maps tend to be more accurate than the cars' GPS, as G-maps are updated more often. More money than sense?
