Pretty much. There's a lot of people doing cool stuff over the radio, but the conventional wisdom is that if it wouldn't work in an emergency, you can't rely on it. So while you can rely on computers somewhat, be prepared to jump on SSB/CW/FM in the worst cases (ie, you only have power for your radio, nothing else). And relying on the internet for anything is an absolute no-no, at least among the emergency people.
