Now that Microsoft has finally integrated at least some of the good parts of Sunrise into Outlook (which I've historically hated, but this is enough to make me give it a look, especially on my phone), I expect they'll be doing the same with Wunderlist for ToDo integration. If, by some miracle, they also manage to integrate great contact management in with the new LinkedIn, they'd really have something... (Aside: They'd have to undo the recent brain damage to LinkedIn first - the value of LI was it's contact info, not the feeds - the last damn thing I want and need is another Facebook-like vanity stream - there are reasons I refuse to do Facebook...)
