This board is, overall, amazing! I would make a few changes in the new revision though. For example, I think the VGA port should be in she same side as the audio jack, and and the USB data channels should somehow be forwarded to the front (same side of the PS2 ports) while the power lanes should forwarded to the back, with VGA and the audio jack. This would make this board more cable-friendly to stand on a table. This isn't in any way a complain, just a suggestion I think would be appreciated by other buyers.
The documentation lacks tutorials for getting started and first steps for kids, this would make the kit more user friendly I think. I would gladly help with that if necessary, as I plan to start creating blog posts about it anyway.

Thank you! Rev.3 moves VGA and audio on the other side.
