Later this week Skype for Windows version 1.4 will come out of beta. Largely it's about two key features. The first is Skype Forward, while the second is the ability to personalize Skype. The two other features are better Skype buttons for web sites and Skype Toolbars for Outlook and Internet Explorer.
Now what the first two mean are obvious. $$$$. Skype needs to start selling minutes in greater frequency and volume. Skype Forward eats up Skype Out minutes. The Personalization options are also for sale in the Skype store.
