To me Drive feels like another part of Google's push to get everything integrated into one easy environment. The end goal is (potentially) noble, but I feel like they are trying too hard to push products out too fast, and a lot of the releases they are making feel quite forced. I don't think that Google and the Google userbase is ready for something like this, and even if this is a really good product I see it failing just like many of Google's other recent products.
