As I sit here, past 3 in the morning, playing with an Arduino for the first time, I find myself thinking...
GOOD LORD THIS IS FUN.
The Arduino folks have this whole thing nailed. The install process (especially for something that involves, you know, buying resistors) was super-easy. The examples seem endless (they have a UDP implementation? Nifty!). The troubleshooting page is relevant and specific. The default environment is so stripped down it hurts, but you know what? I don't care.
This _feels_ like I'm just getting started again, and I'm totally jazzed about it. This whole system is approachable, understandable, and _fun_.
