Three significant points:
- The On / Off button on the front.
- The power supply via a connector identical to some smartphones (former) as Blackberry and HTC.
- The steerable antenna. I would sire if the orientation and size of the antenna is an important value, but its vertical and horizontal orientation has allowed me to slide horizontally in the box audio rack.
Given the good quality of housing and its low weight, it would have been even nicer with a smaller thickness.
