Expect mobile searching to get much easier very soon. Google has been granted patent protection for a new gesture that will allow you to search content on a touchscreen device simply by writing "go" on your device. The search is initiated by drawing a lowercase g and extending the tail to circle the content you want to search. Other search engines could be used by drawing an s instead, or w for Wikipedia. It is a very simple idea, but in a mobile world where cutting, pasting and searching can be cumbersome this could be a real time saver. Google hasn't commented on it yet, but we'd expect to see it in mobile versions of Chrome in the future.
