That's a total black box technology. Basically what they did is said "ok, let's vote using internet, and we'll believe results are true". They do not know is someone hacked them, etc. Voting data from the servers was transferred using personal computer and flash drive of some random sysadmin. It's horrible. In my opinion, they do e-voting for the sake of doing it and being 'first'. Though big thumbs up for e-citizenship.
IMHO, Baltic states are in the forefront of IT technologies. 3G works almost anywhere, 4G in cities. Internet is cheap and super fast (if you do not have 100Mbps connection - you have slow internet connection). You do your taxes, get your doctor appointments using internet and so on, for a very long time (since 2010 at least). All Baltic states have prominent startups, though Estonians where first to sell startup for big bucks (Skype).
