I am planning to buy a Fundamental Logic MaxSerial which I assume is the same or equivalent to Arduino Serial. I prefer to use the RS232 interface to connect it to more devices (including some routers running Linux), but I am also attracted by Arduino Decimilia.
Without considering the USB vs Serial (RS232) interface, What other differences are between Arduino Serial/MaxSerial and Arduino Decimilia?
With the Arduino serial you need to have an external power supply, and you need to add a voltage regulator to have 3.3V output from the board. I think there are no other differences. I am not sure if MaxSerial has autoreset like the Diecimila. I think it has autoreset, but ask Fundamental Logic about it.
