Alignment with the USB ports is not perfectly smooth, somethimes a 2nd or even 3rd approach is necessary when fixing the MBA into the dock. This issue is mainly due to the lack of an “official” dock connector as used e.g. on Lenovo Thinkpads.
Request for improvement:
Please integrate a 2nd clip on the right hand side for the Mini Display adapter, like on the left side for the MagSafe-Connector. It`s not very convenient to plug in this cable every time you dock.
