Comparison of Skype with IM products
[A review published on CNet](http://reviews.cnet.com/4520-9237_7-6243313.html?tag=blog) highlights the main differences between Skype and other IM products offering Internet calls. Although the review is over two months old, nothing has radically changed in any of the contestants by now, so the table is still fairly accurate. Skype is the most localized one of the crowd, supporting over 20 languages officially and tens more unofficially through our [translations forum](http://forum.skype.com/viewforum.php?f=7). And this is a very valid comment.
> Skype is the only messenger to offer encrypted data transfers, making it the most secure instant messenger of the bunch.
The other items unique to Skype in that review are the availability of inbound phone calls (SkypeIn numbers) and no ads in the interface.
