ENTER↑ is a misnomer, long live ENTER:

I'm the same - although when kakima gave an example using [x^2] in the other thread, I said "yes - that's exactly how I would do it". Reflecting on that, I think there's a difference in how I would do something if just reading left-to-right along an expression without any engagement, vs how I perform a calculation that actually has some meaning and relevance to me. I suspect that might also have something to do with the preference for RPN entry over algebraic - RPN makes more sense when the calculation really has meaning, as opposed to just being something you've got to get through for homework or similar.
