This post seems a little too narrow in focus. Sure, there are some hands down winners like white board markers and video dongles.

But your own printer? Coffee and soda at your doorstep? It's healthy to get up, stretch out and walk around a bit. Healthy to socialize in the copy room too.

Are the productivity gains really that great at the margin? I suspect the extra minute you save by not walking to a printer is just shifted to an extra minute on Twitter or Hacker News.

The general concept is a useful one to keep in mind, but as with all productivity pron, there are limits.
