Here's what I'm thinking: in trying to avoid overlap, I don't want to get deeply into the OS itself, nor into the realm of desktops and servers. Laptops I'm on the fence about. So the list of covered areas as I see it would be: 1. Internet tablets (all makes) 2. Entertainment devices (MP3 players, etc) 3. Routers and similar equipment 4. Controls (TV remotes, etc) 5. Cell phones That look right? Obviously the emphasis would be on using Linux (especially embedded) to run mobile and related communications devices.
