Key bounce problems with the HP 15c LE

[Marcio]

Thank you Thomas for your input.

I have been playing with it quite a bit (I'm a power user = I use them a lot) and it seems the double-registering problem is fading out as I press the keys.

The f and g keys being loose doesn't bother me that much though.

On the plus side, yes, the machine is amazingly fast. It computes \(sin(a)\rightarrow y\) and \(cos(a)\rightarrow x\) using Valentin's tried and tricky trigonometrics in a blink of an eye.
