When I was looking for a mobile for my mum, I went to the society for the blind, to see what they recommended for people with poor sight (they cover this as well as blind, and no, I cant remember the organisation's new name either- apologies).
They had a large keycaps print keyboard, and large print (and raised moulding letter) land line and mobile phones.
For myself, now I need reading glasses,whereas I used to print out in 4 point text to save paper. Heck I can still write in 4 point text.
And I agree with I think everything the author and the commentaries wrote. UI changes, not respecting web zoom,...
And for oldish history, I think it was GEMOS that had a setting for how much details the menus and apps had - 3 choices (basic, intermediate and advanced?) with progressively more changeable options in each level.
(And the pain of MS Word having multiple incompatible ways of achieving the same effect.)
