You know a device is due for a refresh when the only thing left to write about it is rumormongering of a possible upgrade . Today it's the turn of AppleInsider, citing sources in Taiwan, to declare that an 11.6-inch LED-backlit display will be headlining a long overdue update to Apple's MacBook Air . We've heard this scuttlebutt before, and the idea that the Air would be shrunken in order to better differentiate it from the MacBook Pro line carries a lot of believability, but we're still a little jaded from previous misleading rumors on the same subject. At least this one comes with all the gravitas of DigiTimes, whose scribes suggest Quanta has an order to build up to half a million 11.6-inch "MacBooks" for Apple in 2010. All that said, we still wouldn't be surprised if Apple let another holiday period go by without updating its unhealthily thin 13.3-inch laptop.
