First, let me state that I'm not criticizing Apple or iMessage, so please refrain from jumping down my throat. I'm simply asking for the perspective of others. I've thought about this a lot, and I genuinely cannot see why it's useful to have all messages sync to all devices. I have an iMac, MacBook Pro, iPad, and iPhone, and I have used Messages since the Lion beta. I find it utterly annoying to have all my devices pinging constantly. Moreover, if I'm done with a conversation on one device, I certainly do not need to revisit it on my other machines. Even after deleting/clearing a chat transcript (through the Messages app and by going into the Messages folder in the Library), there it is sitting on my phone or iPad. I guess I am old school in believing that my Mac should be my Mac and and my phone should be a messaging device. It's worked fine for years. Could someone educate me... why do you want messages syncing everywhere? Maybe describing a concrete scenario where this would be useful might help my old brain to understand. BTW... I'm trying to understand the value of a feature, so simply telling me to disable message syncing is not a valid response. Thanks.
