Here is what I want in a phone:
2) fast enough for normal web browsing, occasional youtube, very light gaming, etc. (do I *really* need dual core?)
3) A good camera.
4) A nice screen (4.3" preferable, 4" min)
The only advantage I see in the bionic is the dual core should be faster. Coming from an original droid I *think* I would be happy with the speed of a DroidX (my Dad's phone). The screen on the Samsung Charge looks super sweet.
Really the only thing holding me back is battery life questions, the $300 price tag, OH and for either phone to be actually released!
