Except by saying no trade in value they are essentially saying it is worth nothing and letting the 2nd had market dictate it.Kind of makes sense to me. By offering a trade in value they are essentially dictating the "base" used value of the product. If they offered a low trade-in value, they would be indirectly admitting that despite being expensive to purchase, the actual value of the product is low. Rather than this, they will just exclude it from the program.
As a current owner, I’ve discovered I’m not the demographic for this. For gaming with a PC I could find a use case for this device. But given Macs cannot game with AAA pc titles and simulators, it’s worthless in my case. I also don’t like a separate battery for it. Don’t believe I will be coming back again for another anytime soon if ever. Apple kinda over promised on this one.
