    But the port replicator has downsides right? Like ideally I would plug into the laptop directly if possible I imagine. 5:10

    If not then could I just theoretically add more ports to my laptop by filling all the ports with replicators?

    Dumb question but why did they start from the front on the TRRS (tip-ring-ring-sleeve) instead of RSST. Just thought I should ask even though it’s pointless lol.
