What is a suitable option for reading journal papers (PDF) and books (upgrading to a laptop with a better screen (e.g. MacBook air), using Android ebook readers, or buying a tablet) to avoid eye strain?

Actually, the CO_2 costs of electronics are mostly associated w/ their manufacture, and the bound CO_2 in a book is quite low, and the CO_2 costs of book (and magazine) production painfully high. Most CO_2 production is for energy. Emissions of Greenhouse Gases in the U.S. 2008-Carbon Dioxide Emissions CO_2 production is a problem for the manufacturing of electronics. The monster footprint of digital technology w/ a ratio of 12 to 1 for energy usage to weight, so assuming a typical ebook reader weighs roughly 9 ozs, so presumably required 108 ounces of fuel to manufacture (on-going energy usage is not considered) Page on epa.gov gives us a figure of 19.4 pounds of CO_2 per gallon of gasoline which equals roughly 16.36875 pounds of CO_2 to make the ebook reader. By way of contrast, it takes ~8.85 pounds of CO_2 production to make a typical book, while the weight of carbon within it is a tiny fraction of that. Page on latimes.com So reading two books on an ebook reader should make it roughly break even, and each printed book beyond that which is not purchased should result in a net reduction of CO_2 emissions, since the Resilience.org page indicates that the embodied energy usage for electronics is much greater than the lifetime usage.

I wouldn't consider this “good news,” because I have no idea how well it will perform.
