Apple has refreshed its line of
MacBook Air notebooks, dropping in more powerful processors and knocking $100
off the price. The 11-inch Air, with 128GB of storage, now sells for $899 and
options range up to a 13-inch screen with 256GB of storage for $1,199. The new versions of the computers, which Apple announced Tuesday, contain fourth-generation Intel
Core i5 and Core i7 processors.
Apple says the new processors
work with its OS X Mavericks operating system to provide 12 hours of battery
life on the 13-inch models and 9 hours on the 11-inch MacBook Airs.
