I saw that board the other day as well. I think I will have to order one to see how well it works.

Although I like arduino because its easy to use with shields. One of my arduino projects was an LED lightbar controller (warning lights for my truck back window). I created patterns for the lights and a make shift remote controller. I think created my own PCB design based on the barebone ardruino design + what I had on my breadboard.

I could have chosen a smaller processor and made it smaller i suppose...
