Thanks for all the replies I use my tablet to read and it is great you can read at night silently turning pages and not disturbing she who must be obeyed I also have about thirty books waiting to be read.
You can also enlarge the text so that you dont need glasses which is a bonus.
But what I am unsure of is ereaders can they also use downloaded epub files and the pluses and minuses of the different types looking to spend about $120 and it must be simple to use as he's an old bigger.
You can also borrow books without leaving home from your local library great for the elderly.
Thanks
