I'm curious how this (and the other button controller) gets away with running the LEDs directly from the shift register with no current limiting resistors? Is the output impedance of the shift reg high enough to limit the LED current itself, and if so does this put undue stress on the shift register?

You do understand that Sparkfun needs to not only make a profit on the parts, but on the R&D, testing, etc for the product right? It costs far more than you'd ever expect to bring a new product to market.
No need to buy it if it doesnt hit your value proposition, I'm sure they will sell plenty at the current price! -
Awesome. I was just a few weeks back predicting that such a product would be a huge hit. I think you guys will discover that that is correct :)
The potential of coupling embedded electronics to android is amazing. -
