Access to the TVM functions in the solver is the key feature that separates the 19B/19BII (don' recall about 18C, but probably it has them too) from all the 17's and 27S. I suppose the Memo function (and truly much easier to use alpha keyboard) is generally seen as the 19B family 'killer app' but only until you try to use it much. IIRC, even using the provided formulas will produce slightly different results than manually using the builtin TVM, probably because the TVM code has some twekas for corner cases, and preserves accuracy in iterative calculations.
