Handy that you can have them fully encased but there’s nothing really limiting any other laptop on this front. You just use an external dongle and have the same flexibility.
Maybe some people really want the enclosed module so they have fewer things to carry, but that’s a pretty small advantage that I’m not sure many people will value.
I could get something like this ( https://satechi.net/products/undefined/products/pro-hub-slim ) for my MacBook Air and come out ahead on weight and size.
