Over the last several years our understanding of brown dwarfs and of the stellar-substellar boundary has changed considerably. We now know that brown dwarfs can be more massive and also may cool faster than originally thought. These new observations of brown dwarfs and very low mass stars both as individual objects and as populations challenge our current understanding of (sub)stellar structure and evolution. I will briefly review the field and then discuss the results of my work at DTM and Las Campanas regarding our new understanding of the stellar-substellar boundary.
