I had received an email from someone who had seen some of my low vision info sites asking me the same question and I put together this for him:

plus recommended he look at my list of ereader "holders" as his mother was a bit frail

I also pointed him to my
Skins, Lap Desks, Stands (and how to make stands) and common ereader dimensions

for reading in bed ideas....
I'm legally blind and I have tried or owned a dozen ereaders and as long as I have at least a 7 inch touch
screen (most comfortable size for me to hold) and a high screen resolution and a GOOD ereader app (like coolreader, one of the few that lets you control tap locations) that lets you control text and background color (gold on black my favorite high contrast settings) plus has a large selection of font sizes (coolreader goes up to 96?) that works well for me

has great info
I prefer an android tablet for its flexibility
and they can look intimidating at first but for using them primarily as an ereader cuts out most of the more complicated actions, if the tablet supports an sd card or like mine a usb flash drive as well you can gather books and constantly update their reading supply for them
my questioner surprised me and went for the nook glowlight instead of an android tablet for his mother (but he later said that was more of a money issue than what he really wanted to get her)
In my case I know of 5 older people who had NO technological experience, who were able to use android tablets (that were set up in advance for them) with the reading apps on a separate favorites page that had no trouble .... my 86 year old aunt surprised me a few days later bragging about her angry birds score
anyway, hope that helps
