You are right, and I said that when the thread started, but I think most people here are looking at this from a server/desktop perspective.
Also, we wanted to have more background on this setting, its history, etc. thus this discussion.
It would be interesting in know what other people working on embedded systems think about this subject, because most examples given are for much bigger systems.
