Palm treo 755p. I absolutely loved that phone. It had the same type of browser that blackberries still have! I missed it until I rooted, but now I'm so obsessed with my Droid that it affects every other aspect of my life.
LG Chocolate vx8550. The second one.
Its battery lasted more than a week. Then again i didn't have Email, Web, and i did not text a lot, due to the lack of a qwerty keyboard. Abc texting was so dumb. I would get absent minded and for get to press the same button more than once.
I love my Droid especially since i can customize it.
