Why does technology/computers improve so rapidly?

An interesting fact is that some manufactures plan for their products to fail because they already have an updated version already. So when you see a new electronic device appear, such as a new ipod, remember that the manufacturer already has a newer, slimmer, smaller version in the factories. They just don't want to sell it yet because they know that after everyone buys the big, dull version of the product, they'll want to go after the new product when it comes out. It's all about rolling in the money.

This is why I think technology seems to speed up so fast. Their simply waiting to sell it after the other sells out.

How is it that people are able to make electronics and computers that are faster and hold so much information in so little time? What makes it so that people can make such incredible creations in so little time? I mean look at the modern computers/tvs/cell phones now compared to them 10 years ago. Its amazing. I bought my computer just last year and for the same price now, I can get something with twice the speed and almost triple the memory and hard drive space.
