Well I argue that point. I love both but I can't imagine running the streets of the Arab spring with my laptop, or trying to keep my phone battery going while I maintain my connection to an IRC network. There are some things where the combination of public, easy to use, short, sms friendly are a big plus for some things. Not that twitter is the only one doing these things or that they couldn't be built on ICR.
