My mom (85) had the Sony T1, but she had problems with the touch screen. It was just hard for her to navigate around and figure out how to do things, and she was constantly accidentally hitting the screen. I got her the K4NT. It is much much easier for her to use. It is lightweight for her arthritic hands, doing things like turning on/off the wifi is very easy, changing font size is just a couple clicks away. It is really designed for a beginner in mind. As far as typing goes, besides her wifi password, which I typed in for her, I don't know of any other typing she will ever do on it. The screen is easy on her eyes, much easier than an screen like is on the Fire. Sending her books through email straight to the device is the best thing ever. She hated having to hook the Sony up to the comptuer. Hey, I'm happy she is even using it, most of the shiny toys I get her sit in her drawer never to be seen again.
Does Walmart still have their deal going?
I hope your mom likes (and uses) what ever toy you get her!
