The steel and aluminum desk (with de-mountable legs, can you say "flat pack"?) is designed so that cables and plugs can be dropped through the gap onto a shallow holding tray. The gap runs the length of the desk so that lamps, phones and laptops can be positioned wherever you want them.
If, like us, you're sold on the idea and already have your credit card out to buy one, know this: Jennifer Newman studios can make a Slot desk for you in any RAL color, but you'll need to contact them for a quote. In this situation, we tend to fall back on our trusty credo: If you have to ask, you can't afford it.
