Question ergonomics, ports are very well separated so bulky USB flash drives can be connected simultaneously. The network port is positioned in the end he leaves hub in the extension of the unit.
The 50cm cable is supplied correct length, it is a bit short for use with a desktop PC but for a netbook / tablet it allows to limit the space.
Question design is quite elegant and sober, but I think the philosophy is rather directed mobility. Now it has a glossy coating that will surely take some scratches over time (especially near the usb ports). A soft touch like "peach skin" as seen on their multi-usb charger 8A would have been more appropriate, but it remains in the order detail.
The size and weight are very suitable for mobility, they are easy to forget, only the cable tidy barely take up more space. However we can replace it with a USB 3.0 cable type B of the desired length. Very good point, no heater observed with use.
To conclude the subject is very convenient for the sedentary and ideal for a tablet like the Asus T100 which has no network connection but a single USB port 3. In the end I recommend, the concept is quite innovative and keeps its promises.
To illustrate, by testing through my local network (via Freebox) I manage to 63Mbps upload and 78 in download via the ethernet port on the hub against 32 and 39 n wifi.
A good idea, use the hub as a "workstation", connect its top devices (keyboard, mouse, external drive, etc.) and connect the Hub when you come home. There are even screens that plug into USB but I do not know if they are compatible, it is not very democratized.
