They just don't want them in circulation. Apple owes no one an explanation and just because they want the machines back doesn't mean they are "desperate" for them. Strange choice of words.I have to wonder, why is Apple so desperate to get these back? Do they have plans for them other than recycling?
You'd think if some dev really wants to keep theirs as a memento, it should be allowed. Heck it saves Apple money since they don't have to give out that $500 credit.
Also you're way too optimistic and giving developers too much credit thinking they'll just keep them as a "memento". LMAO. Many of them would get sold and end up in circulation. Is it really so hard to understand this?
