There are a few problems with using an encrypted volume for everything in your Dropbox/Google Drive (e.g. a TrueCrypt container). For instance, Dropbox's web-interface becomes useless; you can't see any of your files online, and can only access them by downloading the container to a machine with TrueCrypt, then decrypt the volume and retrieve the file you need. This is inconvenient and impossible in some situations. I wish that there was cloud storage/syncing product that catered to paranoids like some of the people on HN. What if Dropbox allowed you use your own public/private key pair for encryption. They would no longer be able to see anything you own, or use de-duplication, but I'd be willing to pay for this added service. And a web and mobile interface would still be possible, Dropbox could even keep your (encrypted) private key in your Dropbox, and then ask you to enter your passphrase to decrypt it whenever you want to access files.
