Apple asked itself what would happen if an iPad and a MacBook Air “hooked up.” Benefits from the iPad? “Instant on… great battery life, amazing standby time… solid state storage… and it’s thinner and lighter.” It’s 0.68-inches thick at its thickest, 0.11-inches at its thinnest, and weighs 2.9 pounds (the old MacBook Air was 0.76-inches thick and weighed 3 pounds). Naturally, Apple is going unibody construction here, with one of those big new glass trackpads. They’re also sticking with a 13.3-inch screen, running at a 1440 x 900 resolution (with an 11.6-inch “little brother” to boot). There’s SSD storage, a 1.86GHz or 2.13GHz Core 2 Duo processor (the same ones available on existing MacBook Airs, apparently), GeForce 320m graphics, and 2GB of RAM standard. Apple says its new “more stringent” battery life tests offer 7 hours of “wireless web” and 30 days of “standby.” Prices start at $1,299 for 128GB and $1,599 for 256GB of storage; they’re available today.
