find the "seven" differences

Quote:We as client of HP expect an official statement with, a) excuses and/or an explanation why it is not possible to make bugs free software, b) a planning for the next bugs free update. In my opinion it's a bad attitude of HP to ignore/not inform there clients.

a) the fact that it's basically impossible, in practice, to make bug-free software has to do with e.g.:
* fundamental physics reasons: trying to limit the growth of entropy is an error-generating process;
* the fact that software is made by us petty imperfect humans, who make mistakes and errors;
* monetary cost reasons: coding with formally proven methods is horrendously complex and expensive, and can only be cornered to code bases with extremely low number of lines. One of the most complex such code bases is seL4, which is only formally proven for a small subset of its targets (and even then, the proof has to assume that the processor's components are running according to their specification), and has the order of magnitude of 10K (1e4) LoC. Modern desktop / tablet / smartphone computers are considered to be running the order of magnitude of 1G (1e9) LoC, or at least multiple hundreds of millions (1e8) of LoC.

b) Tim already explained in the past why neither the development team, nor the management, nor the finance people, are informing users. "Forward-looking statements" and all that legal and finance stuff is one of the reason

FTR, the mere fact that Tim and Cyrille, who are on HP's payroll and are developing HP's calculators, post publicly on user message boards (mainly this one, but occasionally other ones mainly focusing on TI calculators), and are allowed to post something along the lines of "this issue or idea is on the list of things which may be investigated at some point and might even reach the user, should there ever be another firmware release", is already more than what TI, let alone Casio, are doing with their communities of calculator users.
It's a fact that there are contacts between people on TI EdTech's payroll and some community users / programmers, even outside TI's T^3 initiative, but they're private.
