Bing for iPad lasso tool is a rectangle selection tool in disguise

Iwas momentarily incensed at Microsoft when I learned they released a lasso tool. for Bing for iPad (http://itunes.apple.com/app/bing-for-ipad/id418435837?mt=8) that enabled "Circle to Search". Why should that innovation, which existed in the Microsoft Research Project InkSeine (http://research.microsoft.com/en-us/um/redmond/projects/inkseine/), be released for the iPad but not Tablet PCs? My rage subsided when I tried this on my wife's iPad and learned it was less than advertised.

No, "circle to search" is actually a rectangle selection tool with a circular facade. Worse yet, the "circle" is drawn by dragging from one corner to another, exactly how you'd draw a circle on a mouse-based interface. The only innovation here is disguising a cursor-based tool as a touch-based one.
