Yes, why not? Unfortunately all "secure" or "trusted" computing efforts seems to be focused on depriving the owner of permissions and command over the computer, and instead transfer that to large copyright holders. But I suppose the Android security model would make sense, which seems to be based on a traditional unix security model combined with that each program will run as a separate user and having it's own set of group memberships. As long as I don't need to install a rootkit on my own computer.
