The point of RPI is to attach a breadboard to GPIO ports, experiment with sensors/servos and then solder up a project for personal use, or even ship a Kickstarter project.
This board does not have any GPIO ports, much less a massive support community. x86 vs ARM is irrelevant for this kind of custom code. You are not going to be running Microsoft Word or playing steam games on an embedded board.
If anything, an improvement on RPI would be better power management without sacrificing ability to develop software directly on a prototype device. Solar powered systems running on Linux would kick ass.
