What do people think the immediate resale value will be? Due to limited supply how much will they go for on eBay?
If you are a fan, it is a practically perfect device in every way and thus you'll never have a reason to part with one if you are lucky enough to get one. You may be imprisoned or tortured for even considering it.
If you are one of the extremist pessimists, it is worthless and you'll probably have to pay someone a substantial amount to take it off your hands. Nobody could possibly want one because any given pessimist doesn't want one.
If you are someone between the extremes- like me- and lean positive, you might look at the desirability of PS5 with limited supply during Covid. Scalpers on Ebay were getting anywhere from 35%-150% more than retail. If someone wanted a PS5 for about 15+ months there, you had to pay the scalper premium or get very, VERY lucky. The likely-true rumor about Vpro is at least 2024 will be in short supply by a hard limit on how much of a key part can be manufactured. So much like PS5, apparently Apple won't be able to crank up production to undermine any lock by Scalpers for some period of time.
If you lean negative, you might imagine the customizations may limit the aftermarket demand unless those customizations are easily replicated by subsequent owners.
Also, 1st gen products from Apple unboxed tend to appreciate after a decade. For instance, the 1st gen iPhone brand new is going for over $10,000. Will this product be a collectors item?
As in all things with glorious profit stories, the key to success is the rarity of the collectible. Mint Action Comics #1? Retirement money. Best available Honus Wagner baseball card. Little lotto-like prize. One of a kind art pieces by old masters? Big lotto-like prizes.
People then catch on to stories like "1st gen" phone and get ideas about the next opportunity like that. If only a handful follow through, there's probably a windfall in many years. However, if there's many playing the opportunity, there will be many up for auction in that same future... driving down the price because it's not "special" among many others that are identical. Nevertheless, "investors"
fall for the opportunity often.
IMO: too many seem to already be on this same train. Seek out something
rarer, so you can be among the very few with one "new in box" in 15-50 years. This probably isn't that... because too many others may have the very same idea... and perhaps the self-control to actually follow through.
