If you haven't heard of Lightspeed and you're involved in retail, you should make your way to your nearest web browser and look them up.

Lightspeed is a Point of Sale and inventory management software made by XSilva. It combines the traditional Macintosh visual "wow factor" with a powerful relational database backend. Lightspeed uses a familiar iTunes-like interface for its one-click purchasing screen, and allows beginners to quickly delve into drag-and-drop inventory management and reporting. If you've ever used a Mac, you've already taken the first few steps to learning this powerful program.
