I have made a bit of coverage of expansion modules aka docks for use in “expanding” the connection opportunities that are available for laptop computers. These were mainly connected to host computers via the USB 3.0 connector and provided video connections, audio connections along with Ethernet and / or extra USB connections for these host computers, with some of the boxes having removable storage of some form like an optical disk drive or an SD card reader.
Now, Belkin have set up another path between the host computer and the expansion module / dock by exploiting the relatively new Thunderbolt connection primarily used on Apple Macintosh computers. Here, the MacOS user could connect 3 USB 3.0 peripherals, a Firewire peripheral along with a DisplayPort display. There is even an integrated sound module which has an input and output that uses 3.5mm stereo jacks, while the user can connect to a Gigabit Ethernet network segment.
For the Mac user, this may be seen as another more reliable way to “skin a cat” especially when it comes to adding extra deskbound capabilities to that MacBook Air or MacBook Pro.
