The XO laptop is back with a new look and a new design, at least in theory. Nicholas Negroponte unveiled photos of the upcoming XO-2 device this week, with an announcement that the revamped computer would be ready for delivery by 2010 and carry a price tag of $75. Gone is the green plastic keyboard, replaced instead with a second touch screen. The device can be opened to function like an electronic book, or it can be rotated to a more traditional laptop Compaq Presario NX9010 battery configuration, with the new screen assuming the role of virtual keyboard. This flexibility is meant to encourage collaborative learning and play, so that more than one child can use the computer at a time.

The XO-2 will be designed to consume less power and be half the size of the original XO. In addition to its open source Linux-based OS, the machines will carry a dual boot option for loading Windows.

The OLPC group argues the falling Compaq Presario NX9000 battery price of flat panel screens will make the costs achievable. And, in addition to the new model, Negroponte announced the return of the Give 1, Get 1 program in which U.S. customers will be able to buy a laptop for a child in the developing world at the same time as they buy their own. But skeptics are already questioning the viability of the ambitious design and price point, given the XO's history of struggling to meet its goals so far to date.

Making good on a promise from December, start-up battery maker Boston-Power announced today that its almost-too-good-to-be-true Sonata lithium-ion Hp F2299A battery are now for sale, as upgrades for HP laptops.

Boston-Power's claims are impressive: A Sonata cell promises to charge to 40 percent capacity in just 10 minutes (say, the airport wait time from when they start boarding first class until they get to your steerage section). And they reach 80 percent capacity in just 30 minutes.

Speaking of 80 percent, Boston-Power claims that a Sonata will retain that much charging capacity after 3 years, when regular Li-ion cells are down to just half capacity.

The Hp F3172A battery company is very secretive about what, exactly, the magic sauce is, saying only that they have made a lot of little tweaks. So they could well be using unobtanium and unicorn blood. But as long as it works, that's fine with us.

She decided to spend her life making holograms. She went on to earn a master’s at the Massachusetts Institute of Technology’s Media Lab, where she helped develop a groundbreaking 3-D video system (which, incidentally, earned a mention in this magazine in 1991). Then she took her artistic engineering around the world. Sometimes she put it to practical ends, as when she helped the Australian government fix the security hologram on their dollar bill. Other times, it was purely art, as when she splashed a 66-foot hologram of Roman baths across an entire city block in Cologne, Germany. In the ’90s, she even came up with the idea of using solar-mirror arrays in California to project a movie onto the moon (a plan she later shelved after deciding that it would be culturally disastrous to deface something revered by many religions).

While in Germany in her mid-20s, she began to suffer mysterious health problems: scrapes that didn’t heal, kidney ailments usually contracted only Hp Pavilion ZT1000 battery by AIDS patients. As a freelance art-holographer, she lacked health insurance, so she felt she had to switch to steadier work. She went back to Brown to get a Ph.D. in optics, thinking an advanced degree might help her compete in the male-dominated electronics industry. Partway through her studies, though, she found herself nearly incapacitated. “I was going blind, and I was in a wheelchair,” she says. “I thought I was going to spend the rest of my life living with my parents.” Finally, doctors unearthed a hormone-wrecking mass on her pituitary gland—this after years of Hp Pavilion XZ200 battery telling her that her illness was all in her head. “In fact, it was,” she says. “They sucked it out of my nose.”
