Quite true. The ti-84 has a SIG-FIG CALCULATOR option in its SciTools app. It's useful for perhaps teaching sig fig's, but not very practical for actual use. You can only use it for basic arithmetic. The rules for uncertainty for other functions like square root, tangent, or log aren't really suited for expressing results using just sig fig's.
