I've tried that, and the result was maybe slightly better, but still not satisfying at all. So i often have to lift it to read the numbers - and especially the proper position of the decimal point, so I dont mistake it with the commas. As I already mentioned, it depends strongly on where the light source comes from. When I'm working in front of a window, it's the worth case, if the ligth comes from behind or straight over you-it's usuable.
I like the keys, get used to the enter is no problem if you just ar willing to it. But it happens on fast typing that some keys aren't responding - even very seldomly - it makes blind typing to risky. It seems to be a software debouncing issue, because it happens only wenn you press the keys quite fast, even if they are pressed down to the stop. My about 14 Years old 42s doesn't have this behave at all! But maybe the most of you don't have this problem, it's hard to reproduce and maybe only mine has this behave (but I don't think so)
BTW: My 33s has the serial number CNA41109232.
I couldn't resist to open the 33s, and as i saw the soldering of the battery cables, it made me feel quite dissapointed.They would for sure not have kept connected for years, what a "timebomb"! I resoldered all off them, it made me feel safer even if I just use it for spare in exams (I need a working spare calc, not a dead one).
HP have made progress in the RPN-Sector, but not enough to catch up the retrogression they've made thru the past years. Electronic devices have decreased extremly in costs, what has increased for shure are the engineering/developing cost. But this usually are compensated with extremly cheap high-volume production nowadays, so no excuse for HP. For many company's, profit seems more important than image. Sometimes it's usefull to have a non-profit (or not so high)product to keep a good image(and that's the cheapest, best advertising you can get) and make more money with other products, but many managers fail to think so far, after my opinion.
So HP may never reach the level of they're older calcs again (quality, durability, efficiency). Maybe OpenRPN does somehow, as a non-profit organisation?
