i bought my first Mac in 2012, it's a late 2011 MacBook Pro. when Mountain Lion came out, i was happy and relieved that my mac would support AirPlay Mirroring, i know all pre 2011 Mac's got excluded which sucks. so assuming Mac OS 10.9 will bring Siri, possibly iBooks and maybe Maps, is it safe for me to predict that my Mac won't be supported for Siri? im sure 2012 Mac's will be, considering they all got the new Microphones. i haven't been here for awhile, can i expect any other additions in 10.9? and should i expect to be excluded from anything other than Siri??
