I tried the Magic Connector. Similar price to Magic Wand, but it is basically a flat piece of metal the same size as the flat portions of the Apple Wireless Keyboard and Magic Trackpad. The edges are polished and the back (long) edge is rolled, and there is a piece of velcro near that edge. (They don't bother to supply the matching pieces velcro for the keyboard and trackpad.)
The problem with Magic Connector is it seemed to interfere with the bluetooth signal. My Apple Wireless Keyboard showed up on screen as Connection Lost and then a few minutes later Connection Found (or something like that). Over and over. This is using a Mac Mini HTPC from about 5 feet away. As soon as I disconnect the Magic Connector, the keyboard works fine from the same position. I tried contacting the company and so far they have not bothered to return my emails and list no phone number. Looks like they don't really want to have a return policy.
Sounds like Magic Wand does not have that issue? But with both it's a small problem trying to right click. You have to put a finger underneath on the ball and squeeze.
I'm having no BT signal problem with the Magic Wand on my 2010 iMac. It is only two feet from the iMac though.
