Apple loves to push the fact that you can get your items engraved FOR FREE! It seems cool to have your name laser-inscribed on the back of your new device, but you should avoid this.
First, if you decide that your device isn’t worth the money after it arrives, Apple won’t let you return it if it’s engraved. All of the sudden, we know why they’re so generous with this “free” engraving.
Second, a lot of people love to buy the latest and greatest electronics, and a good way to curb the cost of this habit is to sell your old phones, tablets, etc. when you’re done with them. But, you’ll quickly find that companies who purchase your used items don’t want them if they’re engraved! It simply costs too much for them to remove the engraving, so they’d rather not even mess with it.
So, if you’re planning to buy a new iPhone, iPad, etc. for yourself or someone else this year, DON’T HAVE IT ENGRAVED!
