I noticed that when I first started thinking about the Css v tables debate. Google uses a fair number of tables for layout in its designs. Noodle around on Google's site with the web developer toolbar and Outline->Tables->Table Cells. If you're a CSS purist, you'll be horrified. Google's front page makes prominent use of a table for layout. The autosuggest drop down is also a table. Gmail: tables all the time.
