At a run-time of 4:16 this video is wayyy too long for a commercial, but load it and fast-forward to 1:04 and 1:37 to see the awesome Henge Dock in action. It's basically a one-step way to attach your MacBook to an external monitor/keyboard/mouse set-up, obviating the need to plug or unplug every single cable (six in my case) when you want to move it.
I'm curious to try one because I have an extra flatscreen I bought for cut-rate prices from an office that shut down during the recession, and I've been wanting to mount it in my kitchen; sometimes I'm watching something at the laptop on my desk and I want to be able to quickly move it into the kitchen, to continue watching while cooking, and I don't want to run network cables all over the place.
Also, the plugging-a-vertical-rectangle-into-a-slot thing reminds me of something from years ago:
What's freaking amazing is that those cartidges held a whopping 4k and provided hours of entertainment. (The Word file I'm typing this on is 25k and you'll read it for a few seconds.)
