Sure, but it was still an inconvenience to interrupt a presentation once, and another time a prod debugging session where everybody was anxiously breathing on my neck and staring at my screen.

To me the plug placement was an inconvenience, regardless of how invisible it is to you.

On top of that, it never charged in few seconds after years of use, mine would take longer just to connect to the iMac again.

I was glad to buy magic trackpad I could leave connected 24/7 and never think about it (also I liked it much more than the MM in general).
