Thanks for the feedback. I'll see if I can make the images a bit bigger if/when I do an update.

The first reader in this household was a Sony I chose for dad. My reasoning at the time was the same as yours. When that broke and he wanted a new one, I went with Kindle thinking it might be nice for him to be able to use it with his Amazon account. That didn't work out as the damn thing churns out Prime Book Recommendations or something like that and I found that he was accidentally buying e-books he didn't want. End result is I set a parental lock on the device to stop him doing that...
