Yesterday, I have installed the latest version of Skype.I should say this version is very Microsoft. The color scheme got the taste of Metro UI. The key bit is this version can merge your MSN and Skype account together, that is because MSN Messager will be retired next year.
Firstly, I used my MSN account to login in Skype. And then it will ask me whether I have a skype. Of course, I said I had and typed in the details. Then the accounts is merged. I can see the MSN contacts in Skype. That is cool! I do not need to open MSN messenger anymore. That saved some RAM space!
