> While these are experience values and not strict rules: Astonishingly older users are performing better with TUIs than GUIs, and the worst are usually websites and web-applications. By "better" I mean fast in usage and less prone to mistakes. The #1 thing that messes my (elderly) parents up, using a UI, is inconsistency. In modern software, this comes in two main forms: frequent updates that modify the UI, and screen-takeover notices (often about updates that have modified the UI, or to beg the user to perform an update that will modify the UI). These are much rarer in TUIs.
