No, that was a red herring. The iPad 3 with be made completely of soy. The water droplets indicate it will be water soluble and indeed should prove edible. When recycling the iPad 3 Apple will take them and have them shipped to starving children in Africa.
+1 to this.
My wife's iPad 2 looks great after nearly a year with only the smart cover to protect it. The aluminum back only has a single very small scuff from where my 5 year old dropped it on the garage floor. If anything, I really wish they used the same back for the iPod touch.
On a slight tangent, I'm really happy with how the leather smart cover has held up. The leather has acquired a nice slightly weathered look.
Amazon's probably one of the *worst* places to buy an iPad if you live in the US. Amazon doesn't sell them directly and they're all sold through 3rd party sellers at Amazon's site.
Your best bet is via the Apple store online. You'll pay the same, or less than you would at Amazon, receive it quicker, get free shipping and the customer service is good as well.
