In Laptop With a Mission Widens Its Audience, David Pogue raves about the XO:
In November, you’ll be able to buy a new laptop that’s spillproof, rainproof, dustproof and drop-proof. It’s fanless, it’s silent and it weighs 3.2 pounds. One battery charge will power six hours of heavy activity, or 24 hours of reading. The laptop has a built-in video camera, microphone, memory-card slot, graphics tablet, game-pad controllers and a screen that rotates into a tablet configuration.And this laptop will cost $200.
The computer, if you hadn’t already guessed, is the fabled “$100 laptop” that’s been igniting hype and controversy for three years. It’s an effort by One Laptop Per Child (laptop.org) to develop a very low-cost, high-potential, extremely rugged computer for the two billion educationally underserved children in poor countries.
The marketing is equally clever:
O.L.P.C. slightly turned its strategy when it decided to offer the machine for sale to the public in the industrialized world — for a period of two weeks, in November. The program is called “Give 1, Get 1,” and it works like this. You pay $400 (www.xogiving.org). One XO laptop (and a tax deduction) comes to you by Christmas, and a second is sent to a student in a poor country.
Let’s look at the technology:
In the places where the XO will be used, power is often scarce. So the laptop uses a new battery chemistry, called lithium ferro-phosphate. It runs at one-tenth the temperature of a standard laptop battery, costs $10 to replace, and is good for 2,000 charges — versus 500 on a regular laptop battery.The laptop consumes an average of 2 watts, compared with 60 or more on a typical business laptop. That’s one reason it gets such great battery life. A small yo-yo-like pull-cord charger is available (one minute of pulling provides 10 minutes of power); so is a $12 solar panel that, although only one foot square, provides enough power to recharge or power the machine.
Speaking of bright sunshine: the XO’s color screen is bright and, at 200 dots an inch, razor sharp (1,200 by 900 pixels). But it has a secret identity: in bright sun, you can turn off the backlight altogether. The resulting display, black on light gray, is so clear and readable, it’s almost like paper. Then, of course, the battery lasts even longer.
The XO offers both regular wireless Internet connections and something called mesh networking, which means that all the laptops see each other, instantly, without any setup — even when there’s no Internet connection.
With one press of a button, you see a map. Individual XO logos — color-coded to differentiate them — represent other laptops in the area; you connect with one click. (You never double-click in the XO’s visual, super-simple operating system. You either point with the mouse or click once.)
This feature has some astonishing utility. If only one laptop has an Internet connection, for example, the others can get online, too, thanks to the mesh network. And when O.L.P.C. releases software upgrades, one laptop can broadcast them to other nearby laptops.
Some other clever bits:
The built-in programs are equally clever. There’s a word processor, Web browser, calculator, PDF textbook reader, some games (clones of Tetris and Connect 4), three music programs, a painting application, a chat program and so on. The camera module permits teachers, for the first time, to send messages home to illiterate parents.There are also three programming environments of different degrees of sophistication. Incredibly, one keystroke reveals the underlying code of almost any XO program or any Web page. Students can not only study how their favorite programs have been written, but even experiment by making changes. (If they make a mess of things, they can restore the original.)
There’s real brilliance in this emphasis on understanding the computer itself. Many nations in XO’s market have few natural resources, and the global need for information workers grows with every passing day.
Most of the XO’s programs are shareable on the mesh network, which is another ingenious twist. Any time you’re word processing, making music, taking pictures, playing games or reading an e-book, you can click a Share button. Your document shows up next to your icon on the mesh-network map, so that other people can see what you’re doing, or work with you. Teachers can supervise your writing, buddies can collaborate on a document, friends can play you in Connect 4, or someone across the room can add a melody to your drum beat in the music program. You’ve never seen anything like it.
