This article by Macworld Senior Editor, Dan Moren, is absolutely spot on with some of the awkwardness and friction that the Mac Messages app has brought with it. It is great to be able to have iMessage conversations regardless of what device I’m on. But Messages on the Mac has crossed a line between a text message on my phone (something personal) and an instant message conversation (something casual) — the two types of “messages” are not the same. I couldn’t have said what Dan says any better.
