I'm completely new to Android coming from a Samsung Mythic. Don't like the OS. If the TouchWhiz (sidebar feature) is the only feature from Samsung's OS then I would like to get opinions on which AT&T Android phone is better the Captivate or Aria. All I really need is exchange service and a web browser other than the ridiculous default I found in the Mythic. (Since I found it very difficult to add or find any apps that were worthwhile on the Mythic, the only one I used was the Opera browser.)
