There are all sorts of keyboards out there. Mostly, keyboards today are made to be small. But there are some that are made instead to be easy to use – with larger keys, and with visible labels.
Compare, for example, the Mac keyboard that I use day-to-day (the small silver-colored keyboard above), to a more silver-friendly keyboard, which has the same layout, but with much larger keys, and keys that are labeled in a very eye-friendly way.
There are great products like these available. But to benefit, you have to know that these keyboards are available, know how to shop for the ones that fit your needs, and how to hook them up to your system.
