Positive in this Aluständer is that it is suitable for netbooks of all kinds, not only for Macs. It is also good that the part is non-slip, is very stable, the netbook can also be non-slip placed on the apparatus. In fact, you sit very relaxed in front of his netbook when the monitor is at eye level.
Goofy is however about to use the keyboard. If you have to lift your arms as high, which is absolutely inconvenient and annoying.
Thus me the Aluständer appears only suitable when working with the netbook and an external keyboard (which is then available in the usual amount on the table).
