What is Arduino?
Arduino is an open-source prototyping platform based on easy-to-use hardware and software. Arduino boards are able to read inputs - light on a sensor, a finger on a button, or a Twitter message - and turn it into an output - activating a motor, turning on an LED, publishing something online. You can tell your board what to do by sending a set of instructions to the microcontroller on the board. To do so you use the Arduino programming language (based on Wiring), and the Arduino Software (IDE), based on Processing.
I agree, Arduino does not fit the reliable bill. I got several running at home (sprinkler system) and they work well. It would be easy and cheap to have a complete spare laying around, but it is not made for permanent use (in my opinion).

Looks like a neat home project, but I wouldn't deploy something like this in an industrial environment.http://www.velocio.net
