DPP is not bad at all. It is strange, though, that Canon indeed does not distribute it (as well as the EOS Utility program) via internet. When the CD of my old 400D broke down, I could not install these programs anymore. WTF? Without a Canon camera, these progs are pretty useless anyway, so why don't they offer them for download?
As for updating ACR - Adobe almost never adds support for additional file types via updates. I know many photographers - myself included - who are pretty annoyed with that product policy. In theory, this means that whenever you spend a couple hundred bucks on a new camera, you would have to spend the same amount on a new PS version as well. For the money Adobe asks for PS, I would expect more customer-mindedness.
