You are absolutely free to be pessimistic about something you have a fraction of the facts on.
But to ask “A bit rich tho innit? Paying extra for an empty battery compartment?”, well, I can’t answer that. I don’t have all the facts.
I can’t quantify value without all the numbers.
So my question to you is what is the point?
What do you hope to accomplish?
It can’t be answers to your questions, as we don’t have all of the facts.
Are these just rhetorical questions to make the point that you are unhappy that this particular consumer product thing is a disappointment to you, as it symbolizes an overall disappointment with consumer culture (the dongle complaint)?
Either way, have at it! Enjoy!
