It’s a kind of nice feature, but I’ve been a solid magic trackpad user instead since they first introduced the whole magic keyboard/trackpad/mouse set of accessories.

It's better than the puck mouse and Mighty Mouse at least

I vastly, vastly prefer my Mighty Mouse to the Magic Mouse.

The Apple Desktop Bus Mouse II was pretty bad, worse than these. It frequently got dirty and wasn't ergonomic.

The Sun optical mice managed to be both annoying and clever - they didn't get too dirty but the effect was often the same, skipping around when they should have been smooth.

I was a fan of the Logitech TrackMan marble. (I preferred the one with the thumb wheel).

I think Microsoft had some kind of a curved mouse that did that?

Even excluding the puck mouse, I'm sure there are worse mice than the Magic Mouse. It's still not a great product though. Technically it might be pretty clever, but the only way that can parse QA is if Apple exclusively hires testers with really small hands.

It doesn't matter that there's a trackpad on the top, because you can't use it. You'll need to curl your fingers to an uncomfortable degree and there's to little traction beneath the mouse to prevent it from slipping when using the trackpad functionality.

My guess is that the Magic Mouse needs to be close to 50% larger, certainly taller.

The Magic Trackpad however... I hope they never stop making those. That is the best input device anyone ever made. It's large, stable, precise and just a joy to use.
