It's not ideal for a few reasons, but it's what most of the people who play with hardware know, and there are lots of libraries out there for interacting with sensors, displays, etc. If the project gets big enough we may split it into 2 versions, one Arduino and one with a proper RTOS. That said, at this level using interrupts and a state machine is pretty workable, so I wouldn't say multiple threads are a must. Would probably make it easier for regular programmers to pick up and start developing with, though.
