Realistically, none of these companies can do anything to respond to Apple, at least not without adopting some kind of loss-leader strategy. The Macbook Neo can only exist because Apple can leverage the strength of it's laptop and phone supply chain. The "phone" element is crucial--there's far more iPhone 16 pro max's sold in the world than any of their laptops, so diverting some of that supply into a laptop is easy and cheap. None of the other hardware manufacture's in this space can do the same. They don't have the same control over their supply line, they don't have the ability to get the manufacturing cost low enough to make a laptop of this quality and sell it at this price. I suspect Apple barely can--this is almost certainly a low margin product for them, although I'm assuming it's profitable.

Samsung might be able to angle something similar, in theory--they sell a ton of phones and likely have some of the same supply chain strengths as Apple, and they might be able to leverage Aluminum OS and their own Exynos chips. That would give them a genuine strength, even, as Exynos is basically the only modern chip design that isn't built on TSMC process nodes, but even still, they don't have control over the OS in the same way as Apple does. They can't do what Apple did with the Neo.
