Well, I would respectfully disagree regarding the design. Not only is the design an excellent example of essential form and function, but as a production piece, it is durable,far more recyclable, and also I'm guessing, more profitable for Apple.
Imagine a time when old Macs are recylclable, sustainable objects.
I think the case work and interface is stunning. I'm less impressed by the 'front' face, which has no focus on the functional apspects like 'where is the off button?' etc.
The side profile kind of looks like a large X with the new case.
Overall I am amazed at its elegaent simplicity. My guess is that you'll love them or hate them. I hate the G4 Quicksilver case I have. All that plastic is a disgusting use of material.
