Audible.com is giving away some free books, for a very limited time...I guess its till 2nd July.
It takes nothing, juts your e-mail ID and the software it needs to download it. That's it.
Choice of titles is pretty limited, but gives a good chance to get the feel of Audio Books. Looks like I can get used to it.
Following is the like that directly takes to the free giveaway page.
