There's no denying that Apple products are some of the more desirable ones on the market. iPhones, iPads, iMacs, Macbooks, pretty much all of their products have some of the highest resale values in the tech world because they're in such high demand.
A lot of that has to do with just how sleek they are. Remember when the iPhone 4 was first announced? It was a thing of beauty. Super slim, glossy, gorgeous, compact, and just plain sexy.
