Whenever I see a SkydDive review for Windows Phone on tech blogs, they only talk about the app. That's fine, since its a damn good app, but for documents, the built in integration in the Office hub is simply superb. I've used the desktop app at home to move my school work and other important documents, and they appear in the Office hub and I can view them, edit them....no app needed and its super seamless.
I guess the focus for these blogs is on consumer stuff like pictures and music, but for me, the Office hub integration is what makes the SkyDrive updates so compelling. I always loved that OneNote worked so easily across all my devices (laptop, desktop, phone), but before the SkyDrive update, treating documents the same way was just obtuse and dumb, I hated the web interface and hated the uploading process. The desktop app took care of all of that.
