I predict those who are "PC lazy" will love Chrome because they don't need to install applications or keep up to date with any of the security problems of Windows.
They will flock to it and write all over the web about how it has freed them from the shackles of MS.
Then after their data is compromised, or the servers go down, or are overloaded when they need access to a file, or oddly, they will have to pay for the service and/or wade through advertisements, etc....
