Does the HP-35S need a 'guide for dummies' how-to guide?

[MagyarBoy]

Thanks for your comments everyone, I will endeavor to create a guide for the HP-35S, aimed at someone totally unfamiliar with HP calculators (no prior exposure to RPN etc.), and handhold them into fluency with use and programming. (& I should have said this earlier, I am a budding tech writer and I was hoping to market this manual on a website, I hope this doesn't taint my effort in the eyes of everyone here). I intend to make soft & hardcopy available. And I'm not sure how helpful that guide might be for everyone here, as most of the users here strike me as being pretty savvy around HP calculators.
