Google may have started out as a humble search engine, but I use Google Search for so much more than regular web searching. I use it to do currency conversions, to compute basic arithmetic, to check on the weather… the list goes on. It’s also great that you can search through your Gmail, your Google Docs, and just about anything else you have housed on Google’s servers.
It seems that Google is taking a similar “you can search anything” approach to Android as well, because the smartphone platform not only uses Google to search the web, it can also be used to search with just about any application. From right within any application, you can tap on a search button or launch a search widget.
Seek and ye shall find.
