"I reckon "rip off" implies that the seller is making an unfairly large profit margin"

Well I was reckoning it meant paying a excessively high price to listen to music(in my post at least..) The actual product had nothing to do with it.

I think most people who consider it a rip off find little initial value in the value of what makes it cost so much to begin with..

I wanted one long ago, and despite my ability to afford one, there was no way I was gonna pay so much for a music play for my car. That just makes so little sense to me and even the several car audiophiles I know. These days even $200 can bring deliver some pretty good sound.. I understand some people were willing, but most likely most had lots of spare change. Most in the world don't have lots of spare change, so they have to be careful with their spending.

Oh, I met a homeless guy last night who told me he used to think life was too short to not spend his money on frivolous things.
