Fellow SunRay Lovers, I believe the SunRay platform really is the best architecture for "ideal" systems administration. However, video hurts us in a sales point of view. If you have a business of 10 employees, everyone of these employees has the right ear of the boss. This guy decides if, as a consultant, I continue to get paid. If these employees find something like this to complain about and the boss does little real interaction with the same systems his employees use, it is difficult to keep or get this company's business. Many companies operate like this.
On the more legitimate side: I am seeing an explosion for training videos! Three years ago we would get them in the mail. Now some of these places (like certain departments of the State of Florida) refuse! Windows Media is now a requirement. Now I have a bad reputation for telling them this is a great system. So now I ask, "Who would have guessed?" Of course this seams stupid to me but not to the users.
