The AvE teardown mentioned this. It does give you uniform force across the entire work surface, which is theoretically superior, but I think it's a case where a 5% improvement in results does not warrant 75% increase in BOM cost and design, at least in v1 of a relatively virgin market (if the market were flooded with roller systems, you could possibly differentiate with a press based 1.0, but no need to do that out the gate in a virgin market.)

There is nothing complicated about squeezing something out of a bag with with uniform pressure. The book press / screw press has existed since the first century AD.

Here is a 'juicero' that you can fill with whatever chopped fruit you want and get the same/better results:

Oh but does it have the food DRM that forces you to buy all your fruits from one company in overpriced bags?

LOL. That was the fail. They had a tiny market of a subset of rich people whom bought into inkjet/razorblade/K-cup crapola.
