The ballots are much simpler in Canada. I remember getting a ballot that was the size of a 4' x 6' card. Put a check next to the candidate you want as the MP in your riding. Done.

The US ones can be multiple pages where you end up voting for a dozen candidates across multiple federal, state and local offices, plus a number of ballot initiatives. It's kind of nuts.

But I agree the old fashion paper and pen is the best system. It doesn't matter how theoretically secure some high-tech digital voting system is - unless every voter can understand how it works you'll always have people who think it's fixed. Actually, even with paper and pen people will think it's fixed, but you at least eliminate a ton of the unknown because of the physical record.
