Confirm the same - both my parents (avid readers) use iPads with Kindle app or iBooks to read, despite having access to my Kindle3.

From a elderly reader's standpoint, the iPad is like a Kindle DX but a) heavier, b) with color, and c) with tons of other apps. For whatever reason, eyestrain of an LCD doesn't bother them in the least.

I bought a Kindle for my uncle (who has bad eyesight), and he can't use it.

While the books themselves have adjustable font size, menus are way too small for him, and he'd like a much larger screen.

I wouldn't be surprised if he used a 10 inch iPad instead :)
