too many times I've had to text my parents how to troubleshoot their router only to end up calling them and slowly talking them through it. This is not an inherent problem of text, but a problem of synchronous vs asynchronous communication. Round-trip latency of a phone call is much shorter than IM. But I'd say that speech and text still use the same medium (language), so it's not really an argument either way.
