I agree, the e-voting technology should be a lot more secure, but as long as they keep improving it, I don't see it as too big of a problem, but if they used the same technology in the states for example, I would be pretty worried. The influence Estonia has in the world is negligible compared the US, so if something was to go wrong, sure, it would be pretty bad, but compared to the same happening in a more influencial country, it would be pretty minor.
