ELI5: How does a Galaxy S4 cellphone cost $450 when a decent laptop costs $300?

Sure, it's basically a laptop in your pocket, but to make a Galaxy S4 (or the like) would use significantly less resources than making a laptop would. Plus it's 1/16 the size. Why does a little cellphone cost more than an actual computer laptop?

It's for the same reason a decent laptop costs $300 and a desktop with those same specs costs $200. Miniaturization is *expensive*. You not only have to figure out how to cram all of those same components in a smaller space, but you now also have to deal with heat dissipation. And in the case of a phone, you can't really have a cooling fan so you need to find a way to use less energy while also having both cellular and wifi transmitter/receivers. Additionally, phones have touchscreens, which are a fairly expensive component as well.
