Dropbox for Gmail
There's a good reason why Microsoft partnered up with Dropbox. It's exactly because storage is a feature, not a product. It's great for Google or MS if the storage is not provided by them as in the long run, it looks like it's going to have zero margins. If you subscribe for Office365, then it's good for MS if they don't need to subsidize your storage. Same is true for Google.Joel's article comes into the mind: commoditize products that are complementary to your products. Commoditize storage so Office, GApps & the other non-commodity, difficult-to-copy services will have a larger audience. Let companies who provide the commodities struggle and fight each other.
