As someone who buys a lot of "pro" labeled audio gear, the only thing I care about is a bullet point list of specs. I've seen enough snake oil to ignore marketing materials for consumer audio products. But I get why Apple doesn't do that off the bat, because they're not trying to sell these to people like me.
You are not the target demographic for this web page. Congratulations.
Then your "beefy" development machine is less powerful than an iPhone, since I tested it on that, and it works fine.
When I get to a full computer, I'll try it on that. I wonder if the ones I have are "beefy" enough.
I took me zero spacebar presses. There's a big blue purchase link at the top of the page, and it's anchored there and stays with you as your scroll through the presentation.
In my defense, I may have mistaken it for a login button of some kind. Usually the login link goes at the top right. It's uncommon for the "buy" button to be in the top navbar. It's usually at the same level as the product being presented.
