So there's a whole bunch of Thunderbolt docks coming out soon: OWC, CalDigit, and on this site Elgato told us it's coming June 6th. And maybe Plugable and Belkin too. I happened to have an email exchange with a guy who works in the industry, and he scoffed at the current crop of docks. He said they're basically all the same, because they all use the Intel reference design. Performance will be the same, reviews will probably also roughly be the same. And I think he's right, they basically all cost $299. First I was disappointed, but when I thought about it some more, maybe it doesn't really matter so much. They all have a bunch of USB 3 ports, ethernet, DisplayPort etc. and I can't really think of anything I would need more. What do we think about this? Does it matter that they only differ in small details like having SD card slot or not? Or do you buy based on something else?
