After 5 months of waiting eagerly for my machine, within 30 minutes of opening the box, my 10 in screen released from the mount and smashed corner first into the ground; screen shattered. After this completely disappointing thing happened, I started hearing of others mentioning (on YouTube) that the magnet mount is acceptable for the 7" screen, but marginal for the 10 inch. A small bump in the horizontal or vertical might be fine, but a corner bump affecting both horizontal and vertical simply releases the monitor all together.
There are those that have, and those that will. For those that will, I would like to request Onefinity come up with, or partner with someone else, for a more secure mounting solution. I would have preferred a physical (non-releasing) mount over one that has no strength.
