OLPC’s $100 laptop was going to change the world

I don't know how they fared in 3rd world countries, but before OLPC every laptop was upwards of $800 dollars, if I remember right. There were small low-power laptops akin to OLPC's XO, but you had to pay a premium for those. The concept of a $100 laptop was revolutionary (even though, as I remember, they never really got the price below $200, but still!) and it spawned a whole slew of cheap small commercial laptops (generally called netbooks). Chromebooks are a direct descendant of the XO laptop.

I bought one when they came out in 2007 and there still isn't a laptop that I've seen that is a durable as the XO. My 3-year old at the time danced on top of it, threw it across the room, and dropped it countless times and it was just fine. It came with a complete repair manual and you could use standard tools to take it apart and put it back together, which I did for fun even though I never needed to. The membrane keyboard was almost unusable and eventually one of the kids that I let play with it dug their fingernail into the edge of a key and ripped it right off. It would have been easy to replace the membrane, but by then we weren't really using it much.

The screen was pretty nifty for its time. It was dual mode, backlit or frontlit. You could go outside on a sunny day, turn off the backlight and have a high-resolution frontlit, completely readable (though black and white) display. It didn't look amazing indoors and new phone screens are readable both indoors and out for the most part, but again for its time it was amazing.
