Has there been any word yet regarding whether the pre 2011 Macs will be able to support Airplay Mirroring in 10.8? I heard this isn't currently supported and I need to consider whether to cut my losses with this machine and upgrade. Given that I could do with a desktop arrangement sometimes, my options are a bit limited without TB. I'm thinking along the lines of getting a TB display but obviously can't use that with my 2010 machine and a cinema display will constrain my options in the future if I go for a Mac Mini or whatever. Not ever being able to use ApM on this machine sort of increases the arguments for changing my machine (well in MY head anyway...).
