HP 48G+ over 50G?

[Michael de Estrada]

I don't own a 48GX or 48G+, but I do own an early 48SX that I bought new in 1990, that is very similar in terms of display, features, speed and quality and all I can say is that when I bought my 50g 5 years ago I transferred all my RPL programs to it and never looked back. The 50g is truly superior in every imaginable way and the quality is very good. Having an SD card slot makes backup of programs and data very simple as well as firmware updating. In fact, that is one thing I really don't like about the new Prime is its lack of SD card support. The display is much better than the 48 and the processor is much faster. It also has many advanced functions such as matrix eigenvalues and fourier transforms. The lack of USB support in the 48 makes it obsolete, since many modern pc's don't offer direct RS232 port support. About the only thing I don't like about the 50g is it's lack of a good printed manual, and I find myself using the beautifully written spiral bound manuals for my 48SX, since most of the operations are the same.
