The Arduino Duemilanove ("2009") is a microcontroller board based on the ATmega328. It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started.

So why did I buy an "older" board? Because the new Uno uses a ceramic resonator for the microcontroller while the older Duemilanove uses a crystal. A crystal is more accurate and more stable that a resonator, and my application required a very accurate clock source.
The Arduino series of boards all use a crystal for the little USB interface, but they use a resonator for the main microcontroller clock. Why they did this is beyond me. I would gladly pay 50 cents or a dollar more for a real crystal. Also, there is no reason why the one crystal cannot be used for both the USB interface AND the microcontroller (other than increased EMI interference which could hurt the FCC certification - so the story goes), but honestly I think that story is baloney.
Another reason I purchased this board rather than the Arduino UNO is that it uses the FTDI FT232RL USB to serial interface chip. The FT232 works flawlessly at any baud rate, even absurdly high rates like 921600 baud. The UNO board uses an Atmel ATMega 16U2 chip as the USB to serial interface. It only works reliably up to about 115200 baud, then it gets unstable.
Yet another reason I got the Duemilanove board instead of the UNO is that four extra pins from the FT232 serial interface chip are brought out on the board. This allows me to use the Duemilanove as an ICSP programmer. I can also use these pins to send or receive custom data (such as an "on/off" flag to send to the client computer, or to trigger a reset, etc... the uses are almost unlimited).
The Duemilanove may be an "older" board and may be called "outdated", but in my opinion it is much more versatile than it's companion, the Arduino UNO.
So anyway, the board works perfectly as expected... not much else to say about it.
