> You still have to securely distribute those machines.

They're not involved in the tally. Merely displaying and printing a ballot. Which will be verified by the voter. You actually need /less/ security.

> Printing paper is cheap

Correctly managing it's physical distribution is not. We have thousands of poll locations. What if the wrong ballots get used? What if a location didn't get the update delivery? Should we just close it? Use unofficial ballots? Write everything in?

Electronic distribution of ballots solves these very real issues. Please, take some time, and search for common polling location problems and their impacts. You're acting as if they've never happened.

> It is the members of public who validate it

Right. So when the machine _prints_ my ballot then _I_ validate it. We're just moving the same amount of work to a different entity. The one that actually cares that the work is done correctly.

> You are not aware how far away you are from the point!

I don't believe you're actually seeing the point I made correctly.
