The fact that the user interfaces of  Microsoft Dynamics NAV and AX have come to look so similar had lots of media reps and analysts at Convergence Copenhagen 2008 asking Mike Ehrenberg, the chief architect for Dynamics products, whether the two will soon be merged into a single ERP application.

It's a question that comes up every few years in the annals of NAV and AX history, and it always stirs controversy and angst among users of both products, who fear they'll be forced out of a product they are comfortable with, and into something that may not fit their needs as well.
