Interesting indeed. I was considering one of the new Plugable Thunderbolt 3 docks when they become available. I have an XPS 15 9550. I originally bought the Dell TB15 dock, but it was a disaster and I sent it back. The new Plugable ones seem very good (maybe not all the bells and whistles of the TB15) and it looks like they thoroughly test them. These docks were initially supposed to be released in the 1st Quarter of the year. Then they changed it to the 2nd Quarter. Well that has come and gone so I don't know when they will be released. They claim that they are waiting for TB3 "certification". If this article is correct, then the Plugable dock may not have any better luck than the Dell dock unless Dell comes up with some BIOS/firmware updates that finally make things work.
