Creative mode
You can leave the top plate off to allow easy access to the reset button or ISP header. With the top plate removed, you can also use shields that require SPI, such as the ethernet shield or Wireless SD Shield.
Prototyping mode
Leave the top plate plugged in, and you can still easily access all the I/O pins as well as plug in shields. A mini breadboard may be fastened on top for easy prototyping.
