Thunderbolt docking stations have been promised for almost as long the technology has been around, but few have actually made it to market. We’re hoping Sonnet’s Echo 15 Thunderbolt Dock ($400-$550) is a different story: it’s up for pre-order now and slated to be released this summer. Compared to other models, this one packs a huge number of ports: 14 different connection options, plus an optical drive.
