"We have word that Ubuntu Netbook Edition 10.10 might not feature Firefox as the browser of choice, ..."
Sounds like these articles are just looking for controversy.
Granted, I have no idea what info Google has access to in Chrome that it doesn't have in Chromium.
The Chrome beta .deb packages add the Chrome repo to your sources list, so updates are handled through the package manager (no unprompted background updating like in Mac/Windows).
I wonder if there will be any issues including it in the repos because of the integration of the Flash plugin. Then again, for a Linux company, Canonical is pretty willing to use proprietary software where practical.

And as mentioned, installing Chrome will auto-install the Google repo for it as well.
