I'm in agreement, I think Mark stayed too long, and we were too timid about moving into a new areas. (We bought ShareFile instead of dropbox or box.net, we bought Podio instead of BaseCamp, or the real blunder we bought Xen instead of VMWare).
I always worried that Henshall would get the company after Mark and hated the idea of working for a company run by a spreadsheet. I think Elliot will be worse than Henshall, and if you don't get spun off, and you are not directly tied to XA/XD, you need to worry.
I got laid off in Feb 2015 layoff and happy that I'm not having to live through what is going on.
