I just got someone in work to send me a random message from thier iPhone. The first 2 didn't send at all even though they said delivered. Was via I message because the bubbles were blue. I tried sending her a message but it sent as a text. I suggested she turn off I message and back on again. It then worked and was in blue as expected. However it was sent via my email and not my mobile number. This is no problem really but I want to be able to recive and send iMessages from my Mac Pro. I heard once that you can only to that if they use thier email address though. Or should the messages we exchanged appear on my mac when I get home just fine?
