Apple has just sent out an email reminding everyone that "there's still time to add a personal touch" to your iPod or iPad with their engraving service.
It's a nice way to give someone that special gift, but remember that Apple doesn't do returns on engraved devices, so make sure you get the right one.
Here's an excerpt from their email:
Add free personal engraving to any new iPod or iPad at the Apple Online Store. For delivery by December 24, just orderiPad by December 19 or iPod by December 20.
Just don't wait until the last minute. By the way, we have a guide for helping you get through the holiday shopping days.
