That said: all is not good. For years there seems to be a fight going on in the wheelhouse.
One month it is: Microsoft, the reliable, reasonable vendor in a world full of Oracle and Google.

It must be frustrating for the guys who try so hard to drag the rest of Microsoft kicking and screaming into the future everytime some old guys gets up from the wheelchair and turn the weel all the way to the port side while the helmsman wasn't paying attention :-]
