The iOS integration into OS X looks to continue in 10.9 if the rumors of Siri and Maps being included prove to be true.
According to sources speaking with 9to5Mac, both Siri and the critically slammed Maps are coming to OS X 10.9. At this stage both items are in early testing, so there is a chance they will be pulled before the final version of the software is released.
If Apple follows a similar release schedule as the past two years we should see an early build going out to developers in the early part of 2013 for a mid-year release. Once that build is in developers hands we should know a lot more, but seeing as how the company has been slowly working other aspects of iOS into its computer operating system, there inclusions aren’t the least bit surprising.
Just think, you shortly will be able to ask Siri the same silly questions you currently do, just on a bigger screen!
