Microsoft confirms Windows Live Messenger retirement in favor of Skype | The Verge
And I tried on Windows 8, basically you use your Microsoft Account and they will ask you to merge your Skype account. Anyone tried this merge and does the built-in Skype support on our phones still work?
I don't mind MSN start working on my phone, but if it completely breaks it... I do use it for long distance calls.
