The problem is that most users should be more than capable of casting multiple votes. (Though given the average iPhone user - I emphasize average; I know there's plenty who aren't brainless sheep - that puts iPhones at a disadvantage.)

Of course, personally, I was definitely not a supporter of the multiple voting. It's sad. We could have won anyway, I think (going into this, I decided that I would only feel the N900 won if it had more than twice the votes of the Galaxy S, simply because I figured there was a good portion of the demographic who'd vote 2-3 times). I myself was tempted to leave my one vote for the N900, then flood the Galaxy S with however many votes I could generate with the help of proxies from my N900 and laptop. I decided against it because ultimately screwing the the results by others doesn't justify me screwing with results even more, especially when there's probably rabid fans of the Galaxy S doing the same on the other end.
