Is buying market research worth it?
CalmQuiet: I can't imagine how overpriced their services might be. For example, to read a recent story on "10 Reasons IT should Support iPhone" they charge some $739 (summarized & linked within: http://apple20.blogs.fortune.cnn.com/2009/04/13/forrester-to...).Who knows what they charge for their "inside stuff."  
OTOH:  Charlene Li worked there for some 8 years.  They must have some sharp folks.How to evaluate them/their offerings? That's a toughie.
