Google Suggest is similar to using a Help Index feature. I think I like this. As you type, suggestions appear for what you may be looking for. This helps if you can’t spell.
Do you need to translate something, say English to Spanish or Japanese to English.
Try Google Translate.
Trying to find a video of something? Try Google Video. Also works if you are really bored. I did a search for U2 Dallas and found a cool video of the concert I attended.
