I chose to explore the Google Search app - mostly since I've been seeing a number of TV commercials about it lately. Though even as I chose it and was downloading it, I wasn't sure how useful I would find it. I typically just open up Safari on my iPad and use its search feature, and it works just fine. However, because Google is just in general a more robust search engine, this app does provide more than the one in Safari. Things like images, vidoes, news, blogs, etc.
So.... this skeptic may have just turned into a believer! :)
