Office is THE cash cow, OneDrive is (probably) a loss leader. Anything that can be done to ensure Office's continued near ubiquity, reduce usage friction, and shore up beach heads against competitors looking for an area to drive a wedge in will be done.

Well, that's really a new Microsoft.

Just a short while ago, anything that could be done to make their products more integrated, and increase lock-in would be done. It didn't really matter if the benefited product made money or not. (For a very visible blow, look at the Windows Phone and Windows 8.)

It's great to see that changing.

OneDrive on Windows 8+ requires you to use an MS Account for your entire Windows session. So I'd have to pick a short password and do smart card support to use it. That's some pretty lame and obvious forced integration.

Office has always been the exception to that rule. Look at the long, long, long history of Office on Mac.
