Last week I was in Canada and waiting for my flight home I went to the newsagent. There was a science magasine with a title along the line of "science for dummies" (I don't remember the exact title) the cover and main article featured batteries.
I browsed through it and towards the end there was some guy recommending his hp12c and they were saying that the best thing about it was RPN on which that magazine had run an article a few issues before.
