Perhaps. You and I don't care, not yet. I use just about every mainstream Google product/service available. But, we're not most people. Most people are already weary about what they do with their personal information.

There will be a time in the not too distant future when this barrier will be crossed. Giving any large, corporate entity too much information is often perceived as dangerous, because they have a greater ability to utilize/mine/profit from that information than a new startup. I guess we'll just have to wait and see...
