 I'm confused about this remark:

 >   eben's pretty adamant that we *not* turn of the radio using the
 wireless / mesh icons

 His design at http://wiki.laptop.org/go/Designs/Frame#09 shows a "Turn
 off" action for the Mesh icon, and a "Disconnect" action for the access
 point icon. I think these actions should work!

 If they do work, what is the point of having the WiFi chip sitting there
 burning 0.8 watts of our precious battery fluids when both the mesh and
 the access point are off?

 Aha, I think I understand. Eben modified his design with this comment
 buried in another bug: http://dev.laptop.org/ticket/5459#comment:10

 The problem with eliminating the "mesh off" button is that we lose huge
 power saving opportunities.

 I don't think Eben realized that when he made that design choice. See the
 comments in #5144. With the mesh off and an access point on, we save small
 or medium amounts of power -- and have an opportunity to power down the
 WiFi chip when the lid is closed, which saves major amounts of power while
 suspended (basically the laptop lasts much more than 8 hours in suspend).
 With both the mesh and the access point off, the WiFi chip can also be
 powered down during suspend -- or all the time.

 In Eben's modified design, the only way to turn off the mesh is to turn on
 an access point. That's counter-intuitive, and if there is no access point
 visible, there is no way to turn off the mesh at all -- which means we
 burn full power all the time. The "Turn off" mesh action from the original
 design should be reinstated.
