Research firm IHS iSuppli took apart a Google Nexus 7 tablet and estimates the device, which will retail at $249, costs Asus about $159.25 to manufacture. The tablet offers a 1,280 by 800 pixel resolution display. It uses a technology called in-plane switching, which added $38 to the hardware cost. Tablets have the processing power of laptop computers, but act similar to a smartphone. Apparently Google's in-demand device has Amazon considering whether or not to stock it in its online store. Meanwhile, Staples has begun taking preorders for the Google tablet.
