This is Lumia 900- in the teardown performed by the market research firm- IHS iSuppli.
The teardown determined the cost required to build the phone is $209.Now, this is the reason for the launch cost of $99.
The credit of the low material cost goes to Nokia, Microsoft and Qualcomm. The processor was only $17 vs $22 used in the Android phones and 512 MB RAM vs 1GB used in the commonly used Android handsets. The cheaper Bluetooth saved $2.50 vs newer ones of the Android handsets.
Microsoft lowered the prices of Windows Phone OS considerably to $5 from $15 to make Nokia Lumia 900 phone available at $209.
Not much of a difference in the BOM of the two, but a big difference in retail price. Sammy can take a few hints from Nokia on pricing though…!!
