Was it necessary to kill the Classic client?
Absolutely.
The world needs to move ahead. The technology advances. Who doesn’t want to keep up with the progress, stays behind. That’s how it has worked since the dawn of civilization.
I can’t know the exact reasons why Microsoft has decided to stop support for the Classic client with NAV “7”, but I can offer my view and position on why I believe this was absolutely necessary.

RoleTailored client for Microsoft Dynamics NAV 2009 was one of those things for me that looked really nice in presentations, but in real-life, I didn’t see much value there. It looked good from far, but far from good. I would dare saying it saw more runtime at conferences and presentations than in real life. For partners, it was difficult to sell it. With new customers, okay, there were considerable chances the RTC would convince them. With old customers, you were been better-off not showing it at all.
