WIRELESS AND MOBILE NEWS

The stats show that that iPads cost around $260 to make sales have almost doubled since the weekend.

The Chitika Ad Network Labs has their own iPadometer, that shows how many sold, the growth and where they are.  The top iPad state is Apple's home state California, followed big the big Apple New York.  Currently Chitika is showing over 524,000 sold, the numbers are calculated by  counting how many new, unique iPads they detect coming through the Chitika advertising network. Then they multiply that by how much of the Internet they see at any given time to figure out how many iPads in total are out there.

Today, there have been a lot of iPad news stories, the iPad topped Android for Boingo Wi-Fi use, the $29.99 unlimited plan from AT&T will be truly unlimited, music iPad apps are really popular, Wi-Fi issues have been reported.

SugarSync now works with the iPad and whole bunch of popular aps blasted the app store in time for the iPad launch.

Here's the breakdown of iPad costs.

40 percent of its Bill of Materials (BOM) dedicated to the display, touch screen and other user interface components, the combined costs of user-interface-related components in the iPad amounts to $109.50, representing 43.7 percent of total BOM of the 16Gbyte, non-3G version of the iPad torn down by iSuppli.

They call the iPad, a human-machine-interface-centric, with the PCB and Integrated Circuits (ICs) all there to facilitate the display of content as well as user inputs."

Based on its physical teardown, iSuppli estimates the BOM of the low-end 16Gbyte, non-3G iPad at $250.60. When manufacturing expenses are added, the cost rises to $259.60. Teardown costs account only for hardware and manufacturing and do not include other expenses such as software, royalties and licensing fees.

The single most expensive component in the iPad is the display, priced at $65 and representing 25.9 percent of the product's BOM. The display is a 9.7-inch diagonal, 262,000-color TFT-LCD with a resolution of 1024 by 768 pixels. It employs In-Plane Switching (IPS) technology, which supports a wider viewing angle and better picture quality in terms of presentation of color than a conventional LCD.

 he next most expensive component is the touch screen assembly at a cost of $30, or 12 percent of the BOM. The touch screen assembly is 9.7-inches in the diagonal dimension and uses capacitive technology. The supplier of the assembly is Wintek.

Coming in at third in terms of expense is the NAND-type flash memory, at a cost of $29.50 for the low-end 16Gbyte iPad. The NAND in the iPad dissected by iSuppli was supplied by Samsung Electronics Co. Ltd., but Apple likely also is employing other sources of these commodity parts.

The fourth most expensive component is the battery, at $21, representing 8.4 percent of the total BOM. The 3.75-volt battery is a lithium polymer battery pack that employs value-added modular design that combines two cells into a single pack that is more easily replaceable than two individual cells wired in. In the iPad torn down by iSuppli, the battery cells were supplied by Amperex Technology and the pack provided by Dynapack. We had not expected to see the battery cells kitted as a pack, so such a design element clearly suggests these batteries are meant to be replaced at some point.

Design winners Other notable components and suppliers in the iPad include:

•  The microprocessor, combining an A4 processor core and a Graphics Processing Unit (GPU), designed by P.A. Semi--which was acquired by Apple in 2008--and manufactured by Samsung and carrying an estimated cost of $19.50.
•  The Wireless Local Area Network (WLAN), Bluetooth (BT) and Frequency Modulation (FM) module featuring chips supplied by Broadcom Corp. and costing $8.05.
• The touch screen microcontroller from Broadcom, at $2.30.
• A power management chip from Dialog Semiconductor, at $2.10.
• A touch screen driver semiconductor from Texas Instruments, at $1.80.
