 GarageBand now includes several new piano- and guitar-playing lessons. iLife '11 was released on Wednesday as a US$49 upgrade, and is also available free with new Mac purchases. In another move to bring iOS functionality to Macintosh computers, Jobs announced an updated MacBook Air series of laptops, on sale now. The new MacBook Air uses flash memory rather than a traditional hard drive, and has no CD/DVD drive, an approach seen on the iPad tablet computer. In addition, the laptop's battery life has been extended, even though it is only 0.68 in (1.73 cm) thick and weighs less than 3 lbs (1.36 kg). "We think it’s the future of notebooks," said Jobs. There are now two models of the MacBook Air: an 11.6-inch (29.46-cm) version and a 13.3-inch (33.78-cm) model. Analyst Shawn Wu says the company "priced it really aggressively," referring to the computer's base price of US$999. Jobs said that his company sold 13.7 million Macs last year,totaling US 22 billion.
