I've also used this system (Score 3, Informative)

I'm a resident of Nevada and have also used this voting program. I believe it will be the wave of the future. You can actually read the paper 'ballot' as it prints out your results and can double check them against your own choices. The ballot is behind protective glass and when you press "submit ballot" the vote is added electronically and the paper ballot is sucked into a steel ballot box like Augustus through the chocolate tube in Willy Wonka! I definitely recommend this system!
