We hasten to say that we arenit positive that this is what everybody is talking about, but there is evidence that it may be. Applelinks has posted comments from someone who has talked to an Apple tech who saw identical "cracks" all at the same place, starting at the DVD drive slot, going over the top to the edge, and down the side about an inch.
It is unknown how many Cubes have this flaw, but it is clear that many do have it, and many do not have it.
Here are the facts as they relate to my own Cube:
- The flaw is not very obvious. In fact I had to know about it before I noticed.
- You can feel it with a fingernail.
- It does not go through the material, which means that it is not a crack, but a surface flaw.
Now, the most likely explanation has come from two engineers. The latest is from Mac Observeris Wes George, who writes:
I have seen the exact same type of line on very high-end reproductions of certain Bauhaus furniture designs. I was unaware that it was polycarbonate plastic. But the lines were explained away as part of the surface tension that accumulates on the front edge of the molten plastic as it flows around inside the injection mold and meets the front of another flowing surface. The question for engineers is not whether the lines will form but how to design the mold system to place the lines in a discreet location where they wonit detract from the finish productis appeal.
This would also explain why there are similar flaws on both the inner side of the material and the outer side, but they are slightly different. The two flowing masses of plastic would meet almost at the same place on the outer side and the inner, but not totally. In fact this is the only explanation I can think of to explain that fact.
