Thanks for sharing the font size regarding the Kindle, because not one of these eBook manufacturers provides any real type of specs in their advertisements.
I am going to raise hell with Sony and they will either make good on their product, refund monies to me for the books that I cannot read, or they will be dealing with my wrath.
They specifically advertise the reader as being good for the visually impaired, which is only true when they produce the book with the correct font size. Otherwise, the device is useless!
