I dont think it is about the technology at all. It is more about social factors. Enterprises often shy away from being on the leading edge of anything. There is very limited upside and big downside. I'm willing to bet that once the NoSQL space shakes down with some big winners, some defacto standards, enterprises will be adopting it just the same.
Enterprises also need to be sold to. I don't see any startup having a sales team pushing NoSQL solutions inside the enterprise (Amazon's SimpleDB and my own team's Windows Azure Tables might be exceptions).
