This isn't a system administrators' convention here, we're talking about a consumer product aimed at ordinary people who aren't hobbyists. They do not want to learn text-based commands entered at a prompt. It doesn't matter how much benefit they get from it, it is simply not something they would do. They don't give a rat's arse about Maemo itself, they just want a cool gadget that does fun things and is easy to use. Command lines aren't cool, they're not fun, and they're not easy to use.
