You are right. HP 49/50g are some hybrid: they have two modes, algebraic and RPL mode, and in fact they boot in algebraic mode. Most HP 49/50 user immediately after boot change to mode RPL (I do), but some penalty remain: small enter key at bottom right instead of large ENTER key in left middle, bad key arragement or label (this ANS instead of "LAST ARG"). I hate their different key sizes and irregular key arragement, specially when used to HP 48 models being so good.
