iMessages has been a wonderful cross-compatible tool for chatting on iOS devices and Macs - at least until you try to leave your iPhone behind for an Android.
Apple deserters, however, may be lured back to iOS 8 with SMS and voice calls being folded into iPads and Macs, just like blue iMessages currently pop up on Apple tablets and computers.
It's a pain to have to fetch your phone for a single SMS from an Android user, especially when you're sitting in front of a 13-inch MacBook Airscreen that's fully capable of handling text messages and phone calls.
Of course, enabling text messages and phone calls to a Mac requires upgrading it to the newly announced OS X Yosemite, but that's a piece of cake since it'll be free and arrive around the same time as iOS 8.
