Opinions on Benchmade's M2 Steel Blades?

The M2 high speed tool steel is supposed to hold an edge better than most. I'll have to admit, most of my knife questions are stemming from reading a review of a Benchmade 710 on this website:

As always, I appreciate your advice.

Didn't have to look much further than this site to see discussion of the Benchmade 710 <img src="/images/graemlins/smile.gif" alt="" />
