There are many costs involved in the making of these products.
Research.
Studies.
Testing of product.
Having it built, manufactured and distributed to various countries worldwide; all these elements factor into the pricing of the equipment.
Absurd!
Oh, I don't know... Stuff costs a lot to make and without a huge demand for things like the 40K television just yet, the manufacturing process suffers. Remember when BluRay players cost BAJILLIONZ?
As for stuff like the PS3 and Xbox costing that much... That makes no sense. That's downright madness. But I guess if people are willing to pay that much then... whatever. Hats off to the business owner for milking their stupidity. That is, after all, what capitalism is all about.
