The thing still feels flimsy compared to the older products, plain and simple

Calculations are very fast with this Platinum version as compared to the original HP12.

Too bad though as I really liked my first 12C but with the state of the newer versions and how shoddy they have become as compared with what they used to be I have no choice unless massive improvements are made to the current manufacturing processes

I still love the 12c but unfortunately quality is so poor compared to my original that finally died.

Keys still feel cheap compared to my original USA-made HP 12C.

and I notice how the keys are inconsistent, some (obviously more heavily used) are getting loose compared to others and I am not a heavy typist by any means

It's close enough for government work as they say

The 12CP display has thinner characters with less visibility in poor light, and most importantly they lose contrast at even a slight viewing angle as compared to a direct 90 degree observation (important when not directly over the calculator, such as on a desktop).

The keys of the anniversary edition do not respond as well as on the regular HP 12C.
