I also have little interest in what I've seen of embedded Linux devices. I don't really want an MP3 player for my car or anything like that. I think the stuff we're doing with Indrema is really cool, but I'm not into gaming qua "gaming", so I don't need a game console.
So why am I so fascinated by embedded Linux? I don't know. I know why I'm fascinated by Lego Mindstorms, and it's for a related but different reason than the one I can't articulate. I think that my subconscious has a really cool idea for an embedded Linux application, but before revealing it to my conscious mind, it needs a lot of information, thus causing in me a desire to read a lot about embedded Linux.
