Let's say you are a cubicle-dwellling enterprise schulb. You have a repetitive task to perform. Do you:
1) Spend 3 weeks requesting permission to install your favorite programming tools
2) Look around your Start Menu, suck it up and code it in Excel.
(That is ignoring VB's tight integration, first mover advantage, and the fact that an entire generation of kids grew up coding MS-BASIC.)
