As much as many of us like RPN, doing what you suggest would spell the end of the HP calculator product line. They have to design and manufacture the products that will actually *sell*, which means that algebraic is mandatory, because that's what >99.99% of customers want. Those of us that participate in this forum and other calculator enthusiast communities are unfortunately not representative of the calculator market.
RPN is at best optional, and might in some cases be completely unacceptable even as an option, e.g., due to cost of support calls from customers that accidentally put the calculator into RPN mode and can't figure out how to "fix" it.
