Good decision for the future of the project, in my opinion.
When I started Folding the ethos was that any contribution was valued, whether it was one core or 100. The points inflation started with SMP and GPU, but at least these were achievable on a moderately decent desktop and the points weren't totally disproportionate.
The BigAdv points are disproportionate. It sends the message that the project may be called Folding@Home, but Stanford's main interest is in attracting 48-core monsters. A computer which can run BigAdv is not a 'home computer' according to any popular conception of the word, and Folding@Home should be about home computers. Essentially it's changed from a community movement towards renting workstations for free, and I don't see that as a positive development.
