Look at Vijay's assertion regarding his encrypted partition, and how that obviated the need for a trusted element - when the protection of encrypted partitions is one of the primary use cases for TPMs.
You obviously missed my point though, I don't need someone else to "protect" my data, I'm perfectly capable of doing it myself, secondly I only give sensitive data to people I already trust not to give it away, if I have to be reliant on their hardware as opposed to their brain, I probably shouldn't (and don't) give them access to my data anyway. The thing that negates the need for trusted computing are trusted people. If I don't trust the person, I'm not going to give them access to my data; trusted computing or not.
