I use Google Docs, and I like it fine. Apple is taking a different approach which takes advantage of the full power of a native app. The advantage of Google Docs is it works on any computer that has a modern browser. Apple's solution will not have the ubiquity of Google's, but it has the potential to provide a richer user experience. It may be worth it for many of us to buy Apple hardware to get that richer experience, and that is what Apple is counting on.
