Then your understanding is correct :-), I was not making an argument about the relative merits of appliance OSes. The point I was trying to make, and it relates to the linked article that I read and the features they are highlighting, is that the gap between "appliance" OSes and "general purpose" OSes, is narrowing. Both because the "general purpose" OSes are becoming more appliance like, and the "appliance" OSes are becoming more generalizable[sic]. As they get closer, differentiating them becomes more challenging. And I am really curious about how this affects both markets.
