Biggest thing I used it for was phone app to quickly be able to choose facetime over regular call. I also used it alot to scroll through messages, but I know that has been replaced with holding the space bar. Guess we will see. I'm still on the 6s; I'd like to upgrade this year, but also not sure that the new phones have anything in them other than being much faster, that will make it worth it for me to upgrade quite yet.
