> 15 years later and the iPad is still the only tablet anyone really talks about.

When was the last time anybody talked about the iPad outside of a product launch event? iPad sales are falling [0]. It, like every other type of tablet, is a glorified YouTube/Netflix player for most people. It doesn't do anything that you can't already do on an iPhone. Even on "pro" iPad apps like Final Cut, exports are cancelled if you so much as switch to another app during the process. It is in no way a MacOS device.
