I can never quite figure out what the use case is - as I sit here with 2 brave tabs open, my 10.13 mac is using up 13.58gb of ram.
These conversations usually usually end up at "my 8gb ram machine actually swaps constantly, but it's fine because otherwise I'd have to face the cognitive dissonance of justifying this purchase, so I'd rather repeat the apple marketing line they came up with to BS around their poor silicon yields"
