The main problem is that it works in pro tools. I work freelance picking up the over flow work for a company that also has an in house audio suite running pro tools. I insist on running Nuendo because I believe its to be far better (quicker and more efficient etc) than pro tools but it gets very tough making that argument when I have to go back to the editors and get them to redo exports for me that worked fine in the pro tools suite. Unfortunately Nuendo is still in the position that if pro tools can do it Nuendo needs to do it better.
