I hated that feature SOOO much. It was so difficult to grab the mouse without accidentally doing some additional gesture. I'm really glad that feature never caught on.

It did catch on, in that you can still do it with a brand new Magic Mouse on today's macOS.

I use a Magic Trackpad day to day, but back when I worked in an office I would occasionally use a Magic Mouse, and I liked the gestures. (Hated the charging port location, of course.)
