If a goal of distance working is to be environmentally friendly. Meaning less car travel. And working from home is not suited for everyone maybe there is an intermediate solution. The idea is among the buildings close to home companies can rent space for distance workers. The facility would support and cooperate around IT, maintenance and other resources. This way productivity can be maintained with much less travel.
You have probably experienced bad home LED-lights. Those with a blueish cold eye straining color. Therefor I wonder if you can add optimized LED back light that would produce a text on screen experience that is pleasant to look at. The back light does not need to produce light that shows the correct colors. Here the important thing is not put strain on the eyes when reading so maybe it can be a shade of a single color or a warm light. The idea is then to toggle to this mode if you are planning to read a longer period of time on your tablet or feel a strain on your the eyes.
I would like to put forward an idea to further the access to education. There exists a fantastic offline compilation named RACHEL from www.worldpossible.org. It is a large collection of good educational content. It includes Wikipedia for Schools, Khan Academy, Science videos, Healthcare and Medicine videos, CK-12 Textbooks, World Literature Ebooks and much more. If its possible, the idea is to deliver cheap mobiles preloaded with the 32 GB RACHEL compilation. For developing nations I think it could make a difference. It may be naive but I would be so happy if some version of this could be distributed with the cheap Firefox OS phone in a way that complies with the license.
Thinking about this further. For those who only have one smartphone it could be wise to have dual sd-card slots. With this you could then copy RACHEL easily from one card to another.
