Yeah, I'm definitely in love with Google.
That little blank box is truly indispensable to me when I'm working in my shops. Honestly!
For measurement conversion alone, inches to centimeters/millimeters, it's a tremendous help. Then there's the dictionary function, the spell checking it will kindly do for you (yay!) ... but I understand if you have your own favorite way of doing things and change can be painful (you big baby).
So, for now, just take a look at this video. Even if you don't use Google for your home page (you should) for their translator, the widgets, and the features they'll give you for free ... even if you don't, at least check out this video for some quick and unexpected ways you can really utilize Google as a reference tool.
Trust me, you'll never be Google-less ever again.
