Had it ever been determined the problem with missing keystrokes was hardware or firmware related in the current versions of 17bii+ silver and 35s? Maybe both?
I tried to read through the numerous posts here and other places, and what I got from these were that some have problem and some don't.
I did the simple test suggested in other posted by adding up single digit numbers consecutively, keying them in fast enough to cause the problem to occur on both my 17bii+ silver (CNA751...) and the 35s (CNA833...).
At first I thought the keyboards were the cause since I read so many complaints about their older siblings, but then I tried to punch the number keys only to see if they are registered. Neither calcs fail to record the keystrokes.
I performed these tests with both hands holding the calcs and using my thumbs for quickly entering the numbers and the add key.
The test seemed to fail only when doing (+ - * /). My guess is that they would fail for other function keys as well but since their locations are further away from the number keys, I didn't run the test on them. Somewhere in the sequence of number-add-number, one of these keys was missed or not registered.
I know at the end, as far as the users are concern, the problem is still summarized as annoying missing keystrokes, but I wonder if they could be fixed with a firmware update for the next production run. Or the problem is not that simple.
BTW, the tactile is quite good on the 35s, though not the same as the older 32sii/48sx I have. Also, none of the older brothers have missing keystrokes problem, no matter how quickly I hit the keys. They worked every time.
