hp 50G build quality in today's standards (2018)

[TravisE]

Just a bit of an update on my 50g experience: I now definitely consider the keyboard on this product line, if nothing else, to be sub-par. My newer 50g, which had been up until recently working fine, is now also developing keyboard issues like my older unit. Certain keys (presumably the most heavily used ones) are suddenly beginning to register unreliably and cause frequent doubling even with rather high KEYTIME settings (which then make intentional double presses unreliable). This is quite frustrating and disappointing. The TI graphing calculators' keyboards may have been nothing special, but at least they tended to work properly—even after years of constant use. The 50g units, for me, do not seem to age well after enough years roll by.
