Funny how this announcement comes the same week Oracle decided to kill Java EE. MS has always been good to it's developers and broadening the .NET platform this way makes one really consider to give it another look. Oracle in the other hand basically spreads FUD about their own platform, even though they seemingly don't even care about it anymore.
J2EE is widely popular and continues to have a vibrant community. Oracle just doesn’t have the vision of how to encourage and mature that community and turn it into the proverbial golden goose. All they want to do is kill it to get all the eggs today. They can just copy/learn Microsoft’s strategy and come out on top.
