I am now working with the new release of the hp Prime firmware. After a couple of hiccups installing it (due to my using an old operating system in my Parallels session in Macintosh), I finally did. Despite having made a back up of all files and programs, and all literature having warned that data would be lost, the machine still kept my programs when restarting.
Of course, I am not as experienced as other professors, so I am not pushing the device to its limits; and I could not tell a bug from a syntax error; but the machine feels more responsive, seems to scroll better, navigates better through menus, and is in general a better device. Does it feel like an iPhone? Er-no. But it is improving!
The unit that I updated is a G8X92AA, not one of the old NW280AA machines; but the updates are equally valid for both models. You don’t need to change your machine if you’re not going to make use of the Smartstream applications and devices.
The feeling is tha CAS continues to evolve and improve, with the help of Bernard Parisse. I look forward to go through more advanced maths together with my son, when the need comes (last week we had our first attempt to equation systems - a 2x2 very simple case. I don’t want the machine to solve the problems for him -Ci just want him to be able to check the results for now.)
The machine has not restarted a single time since the firmware change. I am now taking it to an extended trip instead of my 41cl. With the initial models and firmware, it crashed several times a day. Over time, it moved to once a week, and now the software seems much more stable.
I need to refer you to the HP site again. I will not keep the newest version in our site, since we cannot ensure that we have the latest software all the time; what we’ll try to guarantee is that the link to the newest firmware remains current.
For us Europeans, there are still things that can be improved. The programs are dependent on the separation character used when writing it. We in center Europe tend to use the decimal comma, and therefore the list and argument separator is the semicolon; but if the program has been written with decimal point, it won’t work and claim syntax error, even though you have been using it in the past. So let’s keep it at decimal point and stay with it. No big deal, but one has to be warned.
The problems existing in some solver apps when using number formats including thousand separators, even with spaces, have not appeared so far -or I haven’t been able to replicate them.
