Old age with Google

I looked up which Apple product brought the company the most income and got an answer that it has been the iPhone.  I have an iPhone but I don’t use it much. I also have an Apple watch but I don’t use it at all.  I am a poor typist, often striking the wrong key or two keys.  But I do use an iPad to check questions and ideas with the internet and with my memory getting more and more fallible and stalled, I am grateful to have access to the Google “search engine” and its results.
