I'd also guess most people will end up with some kind of laptop and some kind of tablet, so no need to choose just one.
...and if I were going for a "laptop + tablet" strategy I'd go for something more substantial than a 12" MacBook as the laptop component. I wouldn't regard an iPad as a laptop replacement but - with a keyboard if necessary - is perfectly adequate for jotting notes at meeting, keeping up with email, even running a "powerpoint" for those times when a MacBook Pro was just too big (...and they're not exactly huge... darned Millennials never tried travelling with a PowerBook G3 grumble grumble..).
Then you have to look at Apple's 2019 aspirations - they're aggressively pushing the iPad Pro as a content creation device, they've got Photoshop for iOS in the works, schemes to help developers simultaneously target iOS and Mac OS, drawing a line between i(Phone)OS and iPadOS, improving keyboard shortcuts, even limited mouse support... That's quite a courageous path when other manufacturers are pretty much dumping the traditional tablet market in favour of 2-in-ones or Chromebooks. So, I'm pretty sure Apple would like potential MacBook buyers to consider an iPad Pro instead (I'm guessing that iPad customers spend more on services...)
's pricing strategy these days it that all products carry 'high' margins. Products like the iPad / iPhone & MB should be priced & advertised as a double/triple solution to make attractive to have both, not either.
