I have a rare Newton solar power supply, capable of running an eMate, and charging its battery at the same time. Sitting in the garden, writing in the shade, cool drink in hand, but with the solar panel sitting out in the full sun, the time passes more pleasantly than when chained to the office desk. Even the battery charges quickly, and no mains electricity is used in the chanrging cycle. Pretty nifty for mid-90s technology.

I have on occasion written academic essays on that eMate. It has the keyboard, crucially, and it's possible to add auto-text functionality and a few other "extras" to NewtonWorks, making this setup surprisingly pleasant to use in a self-denyingly acetic sort of way. Someone with the will could even filter text produced through tools like pandoc markdown at a later stage to make the little machine more "current," as 'twere, but don't think I'll go there myself. Tools from the past, i.e., NewtonWorks and NCU, do the business nicely when called upon from the future....
