Someone sent me an Excel spreadsheet today to my gmail account and google was kind enough to offer to open it in “google spreadsheet” which it did, flawlessly.

Looks like Google needs some kind of Clippy type character that says things like “it looks like your trying to open a microsoft office document… screw those guys open it in your browser”.
I just checked to see if this was happening in my gmail…nope. Am I missing something? I’m all set up with Goodle Spreadsheets and everything.
Any suggestions?
