I've used a 64gb 3G model for almost a year now. I am currently on my iPad 2 and will never go back. The speed is very noticeable. My vote would be to spend the extra $$$ and get a 16gb 3G model. Unless you don't plan to use GPS / 3G. Home share with iTunes is working well so I no longer have the need to store most of my videos. The iPad 2 is crazy smooth. I highly suggest trying it out. With all of that said, I loved my first iPad and could have easily kept using it without regret.
