Development servers are a MUST. I have no idea why except that our gov't is stupid, but, for example, the United States Postal Service website is worked on LIVE!!! The site cannot be that big, for example, I have a 2 terabyte portable drive that should be able to contain not only the USPS site code but the database code as well. If it can't, and the USPS site and databases are more than 2 terabytes, well, that explains why our gov't is so messed up. They made a change in the code about a year ago and NOONE with an account could print a shipping label for over a week. That means that literally thousands of businesses were screwed and a good portion of them had no way to ship their products. If that doesn't convince you that a development environment is necessary, I don't know what will...
