Download Google Chrome?

Even if you google Google Chrome from the Chrome omnibar the first link takes you to the Chrome homepage that asks you to download Google Chrome.

I am surprised why.

You can drag and drop an attachment into Gmail only in Chrome. You can search or translate using voice only on Chrome. Google is also partial towards Chrome when it lets you upload folders to Google Docs. Only Chrome lets you view and print PDF attachments and files in browser.

These and many more such features may have been built with Chrome in mind and may not work in other browsers. Hiding them from non-Chrome is a child's task: it is a one-line check every javascript novice knows, and Google does that.

Why then, in the Lord's name, could they not do a browser check for the Chrome homepage?
