The modular design of Ethernet, SD card reader and optional USB power adapter is a pretty neat design. I think this hub will be my travel adapter as the extra cable length keys you probably won't mind if I need to connect something quickly. You can also just take the black module instead of the whole hub. In the long run I don't really like seeing all the cables plugged into the side of the Mac for desktop settings, so I'll probably stick with my dongle/another dongle-like design.
