You may have noticed that the new Arduino Uno uses the optiboot bootloader. This new bootloader brings two main advantages:
Smaller bootloader footprint - An additional 1.5kB of space for sketches. Increased bootloader baudrate - Faster sketch uploading. Fortunately for us, these bootloader improvements can be backported to the Arduino Duemilanove. If you have more than one Duemilanove to hand, then is it trivial to flash the new bootloader.
