I too see no reason these two things can't exist side by side. The core D&D experience, avec DM and all accoutrements, is what I vastly prefer and would rather play nine times out of ten, and is also what I believe most people will continue to see as "D&D" even with something like Dungeon Tiles available.
Sometimes though, the occasion arises where everyone in the group, DM included, really just wants to kill things and take their stuff.
