I’ve been always uneasy with the “crazy things” Chrome does on Windows, mainly because of my general dislike for apps that disregard important vendor recommendations like where programs should be installed.

I understand that the main upside for Chrome is the unobtrusive automatic updates. What I would like to know is what are the possible downsides. Do you or anyone else know about any discussion about that or research into that?

(By the way, another modern app that uses appdata instead of programfiles on Windows is Dropbox.)
