The letter writer is responding to an article about aging populations and technology. The writer complains that as an 80 year old, they were unable to find a simple mobile phone that only makes and receives calls, without extra features like small keys, video calling, and messaging that are difficult for aging users. The writer argues that technologists should understand not all users, especially older users, want or need complex devices with many extras and would prefer simpler, uncluttered phones that focus on the basic function of making and receiving calls.
