Apple has been one of the top-selling gifts in any category for Christmas this year, according to Amazon's charts. The 8GB iPod touch and its 32GB sibling are not only the second and fourth most gifted items in Amazon's electronics section but (as of press time) in second and third place among the online retailer's bestsellers in any category. They remain eclipsed only by Amazon's own Kindle reader for the top spot in either area.
