The Handoff feature coming to OS X 10.10 Yosemite sounds promising, but it might not be for everyone



From Techradar:

The feature lets users connect their iPhones and iPads running iOS 8 to their Apple computers easily so they can trade files between them with a simple swipe and even make and answer calls and texts from their computers.But according to German site Apfeleimer, the Handoff feature requires those devices have Bluetooth 4.0 LE.This is a newer standard not found in computers prior to the 2011 MacBook Air, as well as the iPad 2, the only iOS device that will be iOS 8-compatible but lack the needed Bluetooth.
