Okay
look at the pic below.
Unless Im hallucinating the part with the silver horizontal stripe is the front of the unit (that is the actual tray).
Now look at the sides one is concave, while the other is convex so you cant set it on either of those sides.
So doesnt that mean if you want to stand it vertically (along side your 360), youd end up with the drive tray on the top? Basically, ejecting the drive would end up with the tray actually moving straight up?
Basically, it appears like it's designed to only be horizontal?
Sorry, I meant tray - which in this case is far worse.
