None. It would look silly to have a grid on the table and then never use it. We've never gamed with minis or the like except a few times to see if it made any major difference or improvement to our 3.x and Savage Worlds games.
What I would love to see (and probably hate to pay for) is a 4'x4' gridded, laminated (or whatever) Table (legs and all) with mini drawrs, done up IKEA style. Ie. order it cheap, assemble it yourself.
