Some skeptics of the Arduino platform often think it's only good for simple robots or blinking LEDs - however with the right planning and engineering knowledge almost anything is possible. One large example of this is a laundromat in Germany whose payment system was modified for control using Arduino and other hardware systems. The entire coin-operation system was replaced with a touch-screen interface from a tablet computer that is interfaced with an Arduino Mega board via some custom circuitry based on another AVR microcontroller programmed in BASCOM.
Furthermore by installing this home-brew control interface system the owner has saved tens of thousands of dollars in not having to replace the controls with the commercially-available unit.

If you're making things that push an Arduino to the limit, or if your projects outgrow the normal Arduino-compatible boards, running out of program and flash memory space, or you're stacking on Ethernet and microSD shields, or all at once - it's time to upgrade to the Freetronics EtherMega:
Quite simple the EtherMega is the fully-loaded Arduino-compatible board on the market today. Apart from being completely Arduino Mega2560-compatible, it includes full Ethernet interface, a microSD card socket, full USB interface, optional Power-over-Ethernet support and still has a circuit prototyping area with extra I2C interface pins. So if your project is breaking the limits, upgrade to the EtherMega today.
