@blogdiva There was another simple and practical reason to dislike the direct recording electronic voting machines (DRE). You can only support as many simultaneous voters as you have machines in the room.
When I was an election official in 2008, we had 8 DRE machines that were basically touch-screen laptops. Each one cost THOUSANDS of dollars. I could support 8 simultaneous voters. No more. Big mad rush? Tough. Wait until someone's done.
Today we use paper and optical scanners. I can fill a room full of privacy partitions, chairs, tables, and pens. I can easily have dozens of people all reading and marking their ballots at the same time. And the scanner is quick.
Big, mad rush? Get more tables, chairs and pens. That's usually pretty easy. Getting another DRE machine quickly in the middle of the day is essentially impossible.
A queue at a ballot scanner is a really different issue than waiting for a turn at a machine that displays the ballot. If someone takes 10 minutes to think through their paper ballot, which is their right, that's no big deal. If they take 10 minutes at one of a small number of DRE machines, it affects other voters.
