You have convinced me of the opposite of what you are stating here. Wanting to know the details has nothing to do with ego. You just like to know the details so you can try to make a *comparison between options*. Details like W/h, delta E, size, sheets p/m, resolution, 2FA, software features etc are factual information that allows for a more rational buying decision. People that cannot make any sense of this are going to rely on different mechanisms to make their choice.

Of course you can present your product in such an attractive way that I hope you will be the winner when I compare you against alternatives, but beware that I will judge it on different grounds. So indeed, communicate details if you want to have a chance to be picked as the buying choice.
