Google tests Web-based spreadsheet to organize dataReuters.com: "Google is joining a variety of Web start-ups that already offer Web-based spreadsheets, including JotSpot, a company founded by Internet pioneer Joe Kraus, Thinkfree Corp. and Smallthought Systems Inc.'s Dabble DB. Microsoft has begun offering its own add-on technology for sharing spreadsheets."

I hardly think Excel Services is an "add-on", and it'll be interesting to see how deep Google's spreadsheet service is.
