That sounds reasonable. So with the OLPC's (pie-in-the-sky) design lifetime of 10 years, maybe it should be compared to 200-300 books. But if you could get thousands of books on a laptop you wouldn't need to know _which_ 200 books a given child would benefit from most.

> (pie-in-the-sky) design lifetime of 10 years I'm more optimistic about this than you seem to be. The OLPC XO-1 has a lithium-iron phosphate battery [0], which are only now reaching the end of their design lives. Anecdotally, I have two XO-1 laptops, and one still has hours of battery life, and the other has only a little over one hour. There is no rotating media. There are no fans. The keyboard is a single piece of silicone rubber. I've dropped one of mine from waist-high onto a vinyl floor, and only a piece of trim plastic popped off. (I put if back on later with a screwdriver.) It doesn't seem unreasonable to me that they could last 10 years in the field, especially seeing as how mine are ten years old and are nearly pristine.
