Hot on the heels of iFixit’s wonderful tear down of the new iPad is a component analysis from the Wall Street Journal.

According to their calculations, parts for the new iPad with 4G total US$309. That’s about $30 more than the iPad 2 which costs $276.27 and the original iPad 3G which totals $270.86.

This extra cost is likely due to the retina display and the 4G LTE chipset, both of which are unique to the new iPad. Which leads us to the question – was Apple wise to up the cost of components and cut its margin in order to give consumers a tablet with a faster wireless internet connection and a gorgeous display?
