Apple debuted the new iPhone 14 series and Apple Watch 8 smartwatches during its September "Far Out" event, then small updates to iPads in October.Now that people have traded in their aging devices for brand-new ones, on Thursday Apple quietly reduced the trade-in values for a lot of older devices.Comparing Apple's trade-in website with an archived version from Wednesday, it seems the company updated the amount of money you'll get if you trade in an older device.It's not surprising that Apple would offer less money to buy back one of its devices, and not just for wear and tear.Now that the brand-new iPhone 14 is on the market, the iPhone 13 -- which was priced at $800 when it launched in September 2021 -- can be bought for $700 on Apple's website."
