The Guardian has an article by Charles Arthur who predicted over two years ago that Microsoft's purchase of Skype for $8.5 billion was 'a gamble unlikely to pay off.' Arthur has penned a followup providing a fairly detailed analysis of his original criticism (he was wrong about some parts), an update on Skype performance, and a conclusion that it's not as bad as some of the other acquisitions. 'Skype, the company points out, now connects directly into Office 365, Xbox, Windows 8, Bing, Microsoft Messenger, Windows Phone and Lync, its business-oriented VOIP solution, and soon into Outlook.com for everyone. ... Certainly, integration of Skype into all those offerings is what the purchase should have been about. And it does look as though Microsoft has pulled it off. ... But has it pulled off $8.5B worth of integration?
