:welcome: to the Droid Forums. So you want to learn a trick? Since you're new maybe you don't know this one. Have your Droid do math for you. No, I'm not talking about a calculator or an app. I mean verbally tell your Droid to solve a problem. Use the search button, microphone, and ask it what 27% of 450 is. Go ahead, you'll get an answer.
Droid Rocks!!! Glad to have you on board.
I just registered and I have had my Droid for about a month and I am still learning things on it so if anyone has some great suggestions or things that are your favorites with the Droid please let me know.
