It's a rugged unit with large buttons and adjustable screen text size, designed for people with limited vision who might need large buttons and possibly a hearing aid. In other words, seniors. I wondered if it might not help the person I'd spoken with, and sent her the link.
Thinking about it for a bit, though, I wondered if having larger type and a rugged phone might not be a good idea for me, too. So I've ordered one. Happily, I could still take advantage of the offer for a free one.
