One of my magnets was loose when i first opened the N900 box for the first time. It was the one at the base. I first glued it with superglue, but it came off again the next day. I glued it again with another sort of glue thats not the thin fluid super glue type that gets hard as glass when it dries. This was November. I have not had any other HW problems, and the magnet is still there.
