I put the blame for today's shitty keyboards squarely at Apple's feet. Some time ago, their laptop keyboards were fantastic! I'm talking about the black Powerbooks. Those really were great machines. Lots of ports as well, unlike today's Apple laptops. Once Apple introduced laptops with the chicklet style keys, that spelled the end of getting decent keyboards in most laptops. And Apple continues trying to make these keyboards even thinner, to the point of developing a keyboard that fails for a large number of its users, forcing Apple to start a program to replace these keyboards well after the warranty expires. I think we're into year four of these butterfly keyboards now. I won't even consider a new MacBook Air or MacBook Pro, not only because of the problems with keys dying on them, but because they are just abysmal to type on. I'd be happy to have a laptop that's a bit thicker than what they have now, as long as it has a good keyboard and a decent selection of ports.
At least with a desktop machine I can choose my own keyboard, and generally use keyboards with nice mechanical key switches.
As for "glass" keyboards, I don't mind it on my phone at all. But for an iPad, I prefer a physical keyboard if I'm going to do a serious amount of typing. I have several iPads (having done iOS development for a while), but I rarely use them. Even if I had a nice, large iPad Pro, I'd still want a keyboard. Apple is making them more compelling as "laptop replacements" (especially with the upcoming iOS 13), but if I cannot easily put it on my lap and type on it, it's not going to work out too well for me. And you can't really do software development on one easily. If I was forced to use a full-size glass keyboard for a significant amount of typing, I'd not be happy. That's one aspect of Star Trek: The Next Generation I don't really want to see.
I love the keyboards on old personal computers. The Atari 800 had a fantastic keyboard! And the one on my first computer, an 800XL, was also good. Then everything went to shit with the 130XE! The 520/1040ST keyboards weren't great, but I love the keyboard on the Mega ST! The original Mac keyboards were also fantastic to type on, and one of my favorites is the Apple Extended Keyboard II. I tried using these with modern Macs (over five years ago) using an Apple ADB (Apple Desktop Bus) to USB adapter, but it could not keep up with my fast typing! I may have to try again to see if those adapters are still being made, and if so, they work better with modern Macs. I still have several of those Extended Keyboard IIs somewhere!
Sorry for the (mostly) off-topic rant!
