Google adds app search to Google Mobile on Android and iPhone
This is great for those times when you don't know the name of a particular app. Instead of Googling to find the app name and then opening up an app store and putting the name in, you get a link directly to the app page. Google says it will only show you app results when "relevant, well-rated" apps are found. The app results include rating and price, so you've at least got some basic app info before you click through. This isn't a revolutionary new feature by any means, but it's a subtle and useful improvement to Google's mobile search offering.
