I just don’t see a calculator as an essential daily app for me, and, if it were, I’d likely need an upgraded one anyway. PCalc, PocketCAS, or something like that. I don’t use the calculator on my phone (instead, I use PCalc), because it’s too basic for my needs.
Sure, it’s a computer, but I imagine very few people even realize their computer has a calculator (or that calculations are the derivation of the word “computer”). Would it be simpler and more convenient for Apple to include one? Well yeah, on some level, I suppose it would be. But, even as a programmer, I don’t need to use a calculator every day. I’d imagine most people using iPads for social media, reading, video, maybe even basic productivity don’t even miss having a calculator.
I dunno, it feels a little like complaining that the iPad doesn’t have an included BASIC interpreter. Yes, that was an essential piece of computer functionality as late as the late 80s (well, Macs dropped BASIC before that, but they still had HyperCard and AppleScript to support DIY consumer programming, with PCs retaining support for it up to the Windows era [well, to today, if you count VBA in Office]), but it is at best tangential to what most people use computers for today. Loading a new calculator app is just a one-time complexity, so it’s not that much more convenient or simpler to have one included. And while you could argue that crunching numbers is essential to how computers operate, so it’s silly the iPad doesn’t offer a calculator, I could easily turn that around and suggest that it’s silly the iPad (or the iPhone, for that matter) doesn’t have a way of running user written code out of the box (since that’s just as much a part of how computers operate as calculations are).
It just seems like unnecessary hyperbole to suggest that an iPad is incomplete without one, even as a matter of principle. Put another way, it strikes me as a silly hill to die on. Who knows, maybe holding this hill really truly is life or death for you, but I doubt many people would agree, and I’ve seen it get used as a bit of an anti-iPad meme on here.
