Udayan, let's please consider content: FM radio is of little use to me - pop culture drivel, bad music, etc. But AM is a different story. It's more interesting. Do any of these formulae change going to AM?
Looking at this article again, I thought of another use for the device. Retune it to the 160MHz band, tweak the software a bit and you have a weather alert radio. Very useful if things get dicey and cell comms is erratic.
I have found that Jan Axelson's website to be a very useful resource for accessing USB devices

Everyone, Thanks for your interesting comments. This is Udayan from Cypress. First of all, the main intention of this article is to bring out the fact that FM radios are not dead. Second, the article primarily concentrated on FM radio as an accessory. The iPhone, iPad, google's nexus, HTC one and most other smart phones and tablets showcased at CES 2012 and MWC 2012, do not have an FM radio built in to it. Manufacturers are slowly phasing out the Radio, the accessory that we have discussed in this article is meant for such devices.
Listening to FM needs good amp and speakers to enjoy its quality.Generally in almost all the devices the FM radio is built in.Recently the refrigerators and washing machines do have this feature. USB based FM applications can go into those who wants to listen when working with their PC's and laptops.A limited application for this design.
Drones are, in essence, flying autonomous vehicles. Pros and cons surrounding drones today might well foreshadow the debate over the development of self-driving cars. In the context of a strongly regulated aviation industry, "self-flying" drones pose a fresh challenge. How safe is it to fly drones in different environments? Should drones be required for visual line of sight – as are piloted airplanes? Join EE Times' Junko Yoshida as she moderates a panel of drone experts.
