It says shipped. Just because there are notebooks that are for sale, doesn't mean they do sell.
I don't doubt that this is more powerful than a 300 pound notebook, but then it's not a fair comparison because this will be more than double the price... Running a mobile OS. We all know how that went for MS. But then, with all the iSheep this will probably still sell.
But I suppose you can't judge the product until you've used it, hey.
