For the last 6 months I have been working with Windows Server 2012 and until now my feelings are very positive. Some time ago there was repeatedly a Windows 8 laptop on my desk. The owner kept asking if I could configure access and install new items, because he couldn't work with it. My experiences with Windows 8 were definitely not positive...at all.
In another (Dutch) forum I was burned down because I stated that the people behind Windows Server understand the direction in which the Windows OS as a whole should be be going, while the consumer guys should not be allowed out of the asylum. Likely it was the last part that did the burning.

Finally, my point is coming...apparently Satya Nadella was at the head of the Server division, so for me his ascension to the throne feels like good news and fills me with hope that Windows will change faster for the better. Not a fanboy here, my network is a mix of Windows and Linux. And it will take a pig, flying through hell with a snowball frozen to its snout, before I will be without my Linux servers.
