...when it [Chrome] offers no advantages over Internet Explorer.
My opinion is somewhat irrelevant to your article, but I guess if you don't see the advantages of extensions or being able to sync your browser settings across multiple computers, and so on, it doesn't have any advantages. Personally, I use those features all too often.
As far as Google partnering up with Adobe and including Chrome in the installation process, I think all users should be aware of what they're installing on their computer. Sponsored software included along with free software installation is fine it's what makes it free. As long as it's not installing it on its own and giving me permission to do so first, I have no problem with it.
