That's basically the problem I have with the Kindle. I love how convenient it is to buy books, and just turning from page to page is easy enough with the physical buttons on my model (or hopefully the little touch zones on the new model), but everything else sucks.
Software updates are rare, the menus are convoluted and obtuse, when the newer models you have to know secret touch zones to use different features. Simple options that used to exist have disappeared and new options of questionable utility have taken their place.
Probably my favorite thing about the Kindle is that it syncs my place with my phone, but the app on iOS is gotten much worse over the years. At this point when reading a book the timeline thing at the bottom and all sorts of weird little blue dots on it that I've never been able to figure out. Sometimes if you tap on one it goes away.
The things just smack of strange decisions. Who thought it would be a good idea to remove the page current buttons for two or three years in a row? And when they brought them back or not real buttons, but hopefully they're good enough.
In the meantime the books are still absolutely riddled with typos, terrible formatting, and if a publisher actually makes an update to a book you're unlikely to find out about it. What little I've heard of the authorship side of things is supposed be pretty dreadful too, were even recent kindles don't support some of the newest formatting things because Amazon hasn't bothered to update them.
It's the best e-book reader on the market, and in many ways it's a piece of crap. It's so clear the decision seem to be made by marketing or something else instead of what the readers want.
And sadly this experience seems to match what I've heard about other Amazon hardware. At best they behave like a mediocre hardware company who doesn't understand software. Even their flagship devices like the original Kindle fire have serious issues, which if you're lucky get fixed in a software update later.
