Is it public demand for continuing lower prices or stupid manufacturers trying to out sell one another and reducing the costs down and down!
It could be that the market place has changed since you used to buy overpriced tech.
In the olden days you bought a TV and expected to still be using it 5 or more years down the track. Tech is now outdated by the time it reaches the shop. Two years is a lifetime in the tech world and the next 'great' must have is always on the conveyor belt. People don't want expensive (anything), they just want to be able to have the latest......The churn enables the manufacturers to keep the prices down....
I'm not saying I necessarily agree with the market place, but, the market place is the market place!!!
