Do Apple send out iPad 2-shaped blocks to "trusted" case manufacturers?
I think this blank mockup was made solely by the case manufacturer, likely based on the CAD drawings we saw a couple weeks ago. Whether these CAD drawings are leaked from the factories or purposefully given out to third party manufacturers, I don't know.
In the comparison photo the iPad 2 is obviously slimmer. Measuring off that photo, the iPad 2 looks to be just under a centimetre deep, compared the existing iPad which is 1.34cm. Of course I am the first to admit this is inexact and depends entirely on the person in the photo holding the iPad flat one atop the other. Nonetheless, I thought I would mention it. Also, despite claims the new iPad is to be a couple mm shorter than the current gen, doesn't it look longer than the existing iPad when you look at the comparison photo?
I hope it still fits in the existing dock, but I doubt it.
