"Life it too short to read the manual"

[Jlouis]

I've just acquired a HP 10bII+, as a suggestion of Tim for some work with statistics and I promptly started to read the manual, even though that life is short and I am already at the 2nd third of the way.

That said, what intrigue me is the fact that, as the OP points out, most people don't want to waste time reading the manual, but, as I saw in the Amazon review of the mentioned calculator, many gave one star for it because:

-the calculator was not working correctly, given wrong answer
-the calculator is almost impossible to use
-the calculator gives an answer for 4^2=4 - This guy even took the time to make an YouTube video showing that.

What I mean is if life is short for read the manual why it is not short to make a stupid review, and making videos showing their stupidity? I'm not offending anyone, everybody is prone to err, but not reviewing and thinking what is wrong with a calculation and starting to spread the lack of knowledge of operating whatever it be is an act of stupidity.
