You could still offer this, similar to the ad tier and ad free tier of a kindle, or a carrier locked phone.
$799 for a locked down version, $1049 for an unlocked version. Opportunity to pay $300 to unlock it later at any time. 5% discount on purchases on a locked device.
they’re gonna struggle to meet demand at $1000 already, i don’t think they need a shitty ad version to support also.
(then again i always buy the most expensive SKU they offer so im very outside the target buyer profile for such)
Fun fact about the kindle ad thing: I don’t know if they still do this but when I got mine, you could just write to the support and let them know you found the ads inappropriate (extra points for mentioning a child in the household) and they would just remove the ads for free.
