I too very recently ran into the problem in the article, and like you, my solutionw as a thunderbolt dock.
I would love however, to have the cordless magic accessoriers, as it keeps the desktop cleaner.
Will give this tool a try if I can get away with installing it on my corp laptop (which forbids any kind of remote access/Synergy-style stuff).
Apple keyboards and mouse are horrible, don’t bother with those, plenty of others exists that also have multiple cordless solutions (dongle, Bluetooth, WiFi). The only of the magic devices from apple that is worth is the touchpad, that one is really good, and yes it is usable with a mouse too, as some things are useful through gestures.
