But what's the error rate? I could type at 200 words per minute (even on a phone!!) if I didn't care about how many typos I was making. And swiping keyboards get confused incredibly easily. The error rates are especially bad when you're writing words that only use a single row of keys - on QWERTY keyboards for example, try writing something like "type", and you could get that, or you might get something else, like wipe/write/ripe. Other groups could include things like tip/top, pit/pot, wit/wire and the selected word will be wrong almost as frequently as it's right. And autocorrect systems can't really correct for things like when you mean to press enter and hit the backspace key instead. Plus, their suggestions are generally just very stupid. So while buttons take longer to press on physical keyboards, the reduced error rate makes typing speed about the same in my experience.

Plus, with physical buttons, you get tactile feedback, so you can tell when your fingers are slightly off and adjust them, whereas on a flat surface, you have no idea whether you pressed the correct button or not. You have to stare straight at the screen to make sure every press is correct, which is exhausting and bad for your eyesight. I feel a lot more eyestrain from simply typing on phones, whereas with physical buttons, I didn't even have to look at the screen, and I could look at something else around me while typing. And don't get me started on how many calls I've missed because I accidentally hit the hang-up button, or couldn't find the accept call button - not a problem when you have physical buttons!

Regarding screen real estate, all you need is a slide-out keyboard. They work great!

There are a few downsides to physical keyboards, but in my experience, they're far superior to non-keyboard devices. But what can you do - in the 21st century, practicality never matters, it's just all about aesthetics and nothing else....
