What's the main blocker (other than the current inflated cost) for using HBM instead of DRAM as the primary memory for consumer electronics?

  Nothing except CPU manufacturer choices. Mac laptops use it and they're consumer products.
  People will have to get used to buying a fixed amount of RAM with their CPU but thats unlikely to be a problem.

    Apple's "unified memory" marketing is so strong that even tech literate people seem to have this misconception!
    They have managed to pull this sort of thing off many many times. <a href="https://en.wikipedia.org/wiki/Reality_distortion_field" rel="nofollow">https://en.wikipedia.org/wiki/Reality_distortion_field

    Yup, the only reason Macs have higher memory bandwidth is because they use more memory channels, which gives them a wider bus. Both Intel and AMD only allow more than dual channel memory on server class processors these days.

    The “Apple only does X better because they do Y” thing has been a meme for ages. I remember dismissals like “PowerPC is only faster at math because it has more integer units” or something along those lines, and thinking, uh, isn’t that a good thing?

    Depends on the expense trade off.
    If I get 10% more performance for 50% more cost it really depends on one's needs, for example.
