Mobile phone for older folks?

Older people have a problem reading the small text on a mobile phone. It is not funny. As there is a large percentage of the population who are old enough not to care about features other than the ability to make a call and read the SMS, I wish Nokia or somebody would step up to the task. Here's my take: the phone doesn't have to be tiny, or pretty. It just needs a big LCD screen and a big key pad. The text should be customizable to different sizes using a physical button that works like the volume button. Yes, the ringer has to be loud too. Perhaps it should have a socket to plug in an earphone, for good measure. What do you think?
