There are a ton of apps we dark matter developers need to mantain that are too massive in scale to port to other runtimes. (wheter it be because of scale of the project or because you have a dinosaur boss in the way (such as my case)) I for example, mantain a manufacturing support application that uses access, and for what is worth, it does processing crap really fast with an sql server back end. Too bad it doesn't support sql batch statements or better vb data structures.
