Interesting question. From the poll results seems like a lot of people think they will remember.
I get the sense that there will be some sort of life review, where everything we have done, the good, bad and somewheres in between may flash before us in a instance.

Guess, I'll find out one day.

Scripture indicates that the sorrows of this present time will fade away and be nothing compared with the joys of the new life.

I believe that in the after life all of our attention will be focused on God, and worshipping him, and loving him that we won't remember our previous lives. I do believe though that we will recognize people we know and family, but none of our previous relationships will matter because we will be with God in Heaven for all of eternity. At that point I don't think how we got there on earth matters, all that matters is that we are able to spend eternity in Heaven instead of Hell. We will be geared 100% to praising God and exploring the new earth that will be created that everything will just get washed away. God created Heaven and the new earth for a reason, he created it for absolute perfection. In that absolute perfection, I think we will be blocked from remembering our sinful past. We will have been washed clean and purified, and remembering this life will just hold us back from experiencing perfection in Heaven with God.
