I found that it ultimately ends up saving deskspace (since the device doesn't need space to move around). I found the device's size to be more comfortable for my hands than the small Logitech bluetooth mouse I was using.
I like the Relacon as a travel device vs. a larger trackball or small mouse because I can move my arm, hand, and wrist more, and more naturally, and still have the same control. I often find myself holding it across my chest or waist, and I can even type (not quickly, but still) while holding and using it. The buttons feel like the shoulder buttons on a Switch joycon, so there wasn't that much of a learning curve.
But, I agree that the out of the box experience, moving only a small distance is very 'sticky'. (Whereas, precisely moving to something isn't difficult).
When I absolutely need gestures, the laptop's trackpad is still there.
As for accuracy, after using a Logitech trackball for about 6 months, I'd replaced my gaming mouse with it for FPS games. The only thing that had a significant learning curve was precise placement of click-and-drag operations, and that was mostly training myself to let my thumb off the ball before releasing the click.
I've never used an external trackpad. I have used the excellent Macbook trackpads.
I'd think e.g. "hold button + drag" is slightly more difficult on a trackpad than a mouse or a trackball.
Rather, I'd say that a trackball feels just as intuitive as a mouse does, whereas a trackpad doesn't feel the same as a mouse.
> How is accuracy?
As one of the replies to my comment points out, the particular model I got isn't very good at small movement. (Many people say they swap out the ball bearings & this helps a lot).
Practically, I found I was able to play games with it without affecting how well I did. https://www.youtube.com/watch?v=D_N_XB5XeDA (I haven't tried gaming on a trackpad; my impression is mouse/trackball are better suited).
