You dont think prices are hiked for Apple consumers? Do a search, right now, for "Apple replacement hard drive", find the best deal you can, then just search for replacement hard drive. Same EXACT product, half the price. Why? Because Apple people are gullible and will pay way more money for the same or lesser of a product because the Apple sticker comes with it. And even if it doesnt, just saying something is for an Apple device, like the above example, is enough to gouge the crap out of the price.
