Im now able to make calls from my iPad mini retina (where before I would get iPhone not available) via my iPhone, I Can start an email on my iPhone 5 and pick it up on my iPad! So far, emails, Safari are working for me, I get a small icon on the left bottom corner of the lock screen of which ever device Im not currently using, I can just swipe up from the icon and boom! Im exactly where I left off kind of cool! Im not sure if its working on Yosemite quite yet given my iMac is a late 2009 27 with the lack of bluetooth LE. Anyone else?
