HP did this 20 years ago, too, with the 49G. But there's probably less of a need now, with all calculators coming with a PC link cable from the factory (when the 49G was first released, I believe it only had a calculator-to-calculator cable, though a 9-pin serial adapter was added in one of the later revisions of the packaging, but I would have to double-check that). So I can see not wanting to waste 3 weeks of engineering time for something that would see such limited benefit anymore.
