Apple's October 20 event should focus on the rumored 11.6-inch MacBook Air with a particular twist in storage, a leak this afternoon claimed. Multiple sources, at least one known to be accurate, said the ultraportable would use barebones SSDs for storage instead of the 1.8-inch fully enclosed drives used now. These wouldn't be as easily replaceable by users, AppleInsider said, but take up much less space in the tight confines of an even smaller system.
