Diebold and other voting machines are basically hacked PCs fit into fancy boxes.

I'm no expert, just an armchair wise guy saying out loud what I think is obvious, but I fear the opponents of electronic voting (in America) are being duped.
The goal of some e-voting opponents in America is to see the Constitution amended to forever enshrine hand-counted paper ballots as the only acceptable way to take a national vote. This would be folly because computers could, and should in my opinion, be used to take the modern liberal-democratic system to higher, more democratic, levels.
There is nothing inherently evil about computers, and they do keep count better than humans. If voters were to, rank election candidates, or score them, or something other than just support one in a winner-take-all contest, computers could be used to find the "winning" candidate who could best represent the will of the voters. That would be the moderate candidate in many cases, but it could be the progressive candidate when society faced danger or rapid change.
The topic of alternative voting systems is apart from the point I hope to make, but just Google "range voting" or "instant runoff" to get an idea of what alternative voting systems can look like. Instant runoff voting is making currently making headlines on OEN and, one would hope, in North Carolina. The first-past-the-post voting system in widespread use today is just about the least democratic form of representative democracy possible, and, on top of that, we allow it to be corrupted in its core principles by licensing private companies to operate electronic "black-box" e-voting. It really is hard to believe, and I suppose that is why so few people pay much attention to these issues.
Moreover, we could, and probably should, be talking about things beyond the voting system. The ancient Athenians rejected representative democracy itself as being too corruptible. Their chosen form of democracy was much more participatory. Lots were drawn to form a Council of Five Hundred. This powerful group then proposed laws that all the "citizens" could vote on by showing up on frequent voting days. This system worked so well that the word democracy was given a positive shine everlasting to this day. Imagine how much better a job we might do on the environment if we resurrected their system.
