I ‘m watching my old 38G. A very nice shell design, durable, keys with the real HP touch, keypad not overloaded, and a very nice and readable screen. But the software is very limited. It does not allow variable names longer than one character, does not offer thousands separator.....
Would it not be possible to develop an operating system or two, making this hardware to a true successor of the scientific and business series? One hardware, two or maybe even more different operating systems and software. You buy the "empty calc" or just a basic functionality and download the operating system and software from the net according to your needs and pay for the download. You could select UPN or algebraic implementation, it should give you some graphical capabilities and it should clearly be much simpler and more user-oriented, than the 48/49 series. Similar solutions are available for some PDA’s, however without the dedicated keyboard and design of a real calc they remain unsatisfactory for serious use.
Just an idea…
