That makes no sense? It’d certainly far easier and cheaper for Apple to put out an iPad in a notebook form factor that runs iPadOS than to make a Mac that runs macOS on an Axx processor with limited resources like RAM and storage - unless it’s an expanded design that bridges the two types of devices, but it sounds like a big R&D bill for an entry-level product that is supposed to compete with cheap devices like Chromebooks.
Yeah I don't mean to be insulting but you reeeaallly don't know what you're talking about, and I mean that genuinely, like you are just very unfamiliar with how things work.
"an Axx processor with limited resources"
Right now the current iPhone Pros use the A18 Pro chip, but in a few months the iPhone 17 will be introduced with a new chip meaning Apple won't need the A18 Pro chip for the iPhone 16 line anymore. The iPhone is, by a huge margin, Apple's most popular product. So it'll be much much cheaper for Apple to continue using the manufacturing lines of the A18 Pro for a new device such as this. Eventually it'll get more expensive for Apple to continue manufacturing old M1 and M2 chips etc because those are made on an older process, the A18 Pro is manufactured using the same current process as the M4, plus the A18 Pro is a smaller die compared to the M4, which will make it cheaper. From every angle Apple using the A18 Pro is the smartest choice, it's cheaper and easier to manufacture, and has the single core performance of their current lineup, which is the most important for a device like this, and be much easier to continue giving software support to. The M4 is already overkill for the vast majority of MacBook Air buyers, and a MacBook with an A18 Pro will also be overkill but much closer to majority of user's needs while saving them money.
"easier and cheaper for Apple to put out an iPad in a notebook form factor"
This again makes absolutely no sense. What exactly is an iPad in a notebook form factor? An iPad with a Magic Keyboard? (which already exists) Or literally a laptop, so a keyboard and trackpad permanently attached to a display, but you're saying that display has a touch screen and runs iPadOS? Again that just makes no sense and I have no idea where you're trying to go with that. Why on earth would anyone want a device like that? Apple is not that stupid and it goes against their entire philosophy of what makes an iPad and iPad and a Mac a Mac. Plus how do you figure that would be "much cheaper for Apple"? If anything that would be more expensive for Apple.
"sounds like a big R&D bill for an entry-level product"
This is exactly why I said this new MacBook will either use the 12" MacBook chassis or the M1 MacBook Air chassis, or something extremely similar to either. Because all the R&D is already done. Apple designed and released the 12" MacBook 10 years ago, and the previous MacBook Air design 8 years ago. These are old designs and Apple using an old design will save them a ton of money because they don't need to spend a lot in R&D, which will allow them to price this MacBook super cheap.
Everything about this rumored device makes perfect sense, in every single way it'll be super cheap and easy for Apple to produce and give them a way to get a MacBook to people for much cheaper than they could have before. It'll be just like how they're currently selling the M1 MBA through Walmart for $650 but they'll sell this one themselves directly and discontinue the M1 MBA entirely.
