As people on MacRumors keep chiding me, Apple is often late on features, but better when released. So I am very excited to be able to start doing all the calculations that I needed to do and had accumulated over the past decade+ when this app arrives.
For years and years and years and years, all my non-Apple friends kept breezing through calculations and enjoyed many other apps and features to enhance their lives and careers, but I laughed at them and told them that when I get these features from Apple, it will be better than what they have enjoyed all these years. And then they will be jealous of me.
Of course, Apple could have offered these same apps and features on the first day along with everyone else and then improve upon them to get ahead. But then I would have had to suffer an imperfect user experience when I could just wait about 10-15 years for a slightly better experience.
But I don't totally blame my non-Apple friends for not understanding this. I wouldn't have known to think this way if not for my friends here at MacRumors.
