Do you have an Hp39G? (I have an Hp39G and Hp40G and not the Hp39G+, so take my comments accordingly).
It is the same hardware upgrade the Hp49G+ is to the Hp49G (upgrade is debatable, as while the 49G had rubber keys, they worked). You get a much faster calculator than the 39G with a much better feeling keyboard (whether it suffers from keyboard problems like the Hp49G+ did, I don't know). It has a USB port and is aimed at the HS market to compete with the Ti-83. That said, it has a much deeper set of math functions (aside from statistics functions, which the 83 is an excellent calculator), but is also limited in features so as to not be banned in schools (27 variables only, no units conversions, etc.)
It is an algebraic only calculator, and would be a big step back for an experienced Hp48/49G series user. That said, it is fairly easy to use and has an eq viewer (not an eq writer, which is present in the Hp40G series with the CAS command, a mistake to leave out in my opinion, but again, Hp wanted to compete with the Ti-83 series).
It is a very appealing calculator from a cosmetic point of view (I think it is the nicest looking Hp I have ever seen, but it also proves you cannot judge a book by its cover).
Just my 2 cents.
