Where is SaaS on the Tech Adoption Life Cycle?

I listened to a webinar on high-tech marketing recently in which the Chasm Institute discussed the Technology Adoption Life Cycle (TALC), saying that it is the Pragmatist segment that ultimately decide on the success of a high tech solution.

There has been a lot of talk in recent months about Software-as-a-Service (SaaS), but has anyone agreed where on the TALC that SaaS is?

Where on the TALC do you think SaaS is?
