Pam explains Software Magic in GP 2013. I was sitting at iSight with Errol Schoenfish a few years ago when I heard about the possibility of a carving up GP in a way that would create a web client. I wasn’t sure it was possible but with all the Dynamics products engaged in a race to the cloud, I hoped it was possible. Now we have the imminent release of GP 2013 and the first iteration of the web client.
