And before you mention it, yes the charging cable. In reality, plugging it in for literally 1 minute will get you enough battery to last hours. 5 minutes will get you an entire day. Normal people plug it in and go get a coffee or pee and then it’s fine until they log off for the day. Could it better? Of course, but it’s not so large an issue that they are losing customers on it, so it is what it is.
You’re not the target market for an Apple mouse and that’s okay.
Unfortunately I had to learn this when I got my first mac.
You don't have to go very deep into the ecosystem to encounter things that... well, things bottom out at shallow.
Looking back... glossy displays. flat keyboards without curvature to center your fingers on the keys. more and more hurdles to using macos as a technical person. prematurely missing USB-A. memory/storage that's not expandable. Dongles everywhere as a checkbox item/workaround.
and of course, anything that superficially seems to be a mouse.
It's also the terrible ergonomics.
It's the epitome of putting form before function. It's a desk ornament that leads to frequent injuries with use. See: https://www.google.com/search?q=magic+mouse+injury
It is neither a good trackpad replacement nor a good mouse design.
With a large enough trackpad, you could even move to a 1:1 type of movement, or add that functionality to a layer for the best of both worlds (like gyro enhanced aiming in games).
I’ve worked with some designers who did what you described with their huge tablets. Use the stylus to turn it into a giant touchpad. Works pretty good.
