I think mine is very pretty also. It's just not blue.
I use a module for the USB/Serial, so you can have one or not, onboard or offboard. Battery-backed RTC, fully buffered SD card, RS232 buffer and 3-pin header to connect to +/-10V RS232 signals to a DB9 connector, prototype area to add some circuitry (such as a 433 MHz Rx or Tx board, or nrf24L01+ board, or an IC or some LEDs), signal-power-gnd at each header location next to each female header, jumper selectable DTR enable signal, jumper selectable or 5V regulator power selection and optional screw terminals to connect to all 32 IO and 3.3V, 5V, Gnd. Unused gates in the 5V to 3.3V buffer and the 3.3V to 5V buffer are also brought out for access.
I have a different design philosophy. My goal was to create a great base unit with lots of 5V, 3,3V and ground connection points, all programming interface headers populated, and both male and female pin headers. Getting all the necessary/important pin peripherals printed on the board was also important. If you need extra functionality like RF, RS232, RTC, SD card or Wifi functionality, you can just hook it up when needed. External modules are literally free if you buy them on the interwebz :) IMO a development board shouldn't be used in a finished product/project. You would ether design your own PCB for this (etch yourself or get it manufactured) or use a photo board. It's MUCH cheaper ;)
