The problem, as I've described on my blog regarding the Nielson/Netratings proposed metric, is that it can be artificially inflated very easily with no clearly measurable margins of error (http://agentultra.com/?p=70).
The great thing about page views is that we can parse out (with a level of certainty) which views were accidental browser refreshes and so forth.
There's also potential for gaming such a system that Nielson/Netratings proposes. One just has to look at Second Life and the problem it has with the "time spent" model. It spawned the "camping chair" where land owners would pay out a minimal fee to people who would hang out on their land.
The trick is to use multiple sources and to be good at statistical mathematics. :)
