Great, now I can buy a Thunderbolt dock offering all the ports that a computer should already have! Okay, maybe for a laptop this could make a lot of sense, though personally I'd rather see more Thunderbolt display options with these ports built in for that purpose. I also don't see why they couldn't fit internal power in this device; it's pretty big for a bunch of ports and shouldn't have any major cooling needs; this just gives the impression of yet another "premium" Thunderbolt device that is cutting corners by not designing AC-DC conversion into the actual product.
