I use Nuendo 100% for music production.
But there is some truth in the point that there might be more Cubase-music users than Nuendo-music users. I purchased Nuendo around 2001 and at this point Nuendo was something completely new and different to Cubase - audio-related.
Today I would most likely be fine with just a Cubase licence. No need for Schneck and way cheaper.
I think Nuendo+NEK users should be allowed to post over there at the Cubase board - there are WAY more music users then here I would say. This would just make sence.
