What are some good smart phones for at&t?

For the past two years i've been using the LG Xenon and now my contract will be up in August so i'd like to upgrade to a smart phone. My current service is at&t and I can't pick which smart phone I want. For awhile I was choosing between the Motorola Atrix and the Samung Infuse 4G and later chose the Motorola Atrix but after reading some reviews I wasn't sure anymore. I would like a smart phone with a great battery I won't have to charge everyday, with fast internet with possible adobe flash, with a good camera with flash, and that's touch screen. NO IPHONES! Thanks to anyone who reads this and gives me suggestions.
