the electronics are lovely but useless when casting your vote.
probably the safest method is manually marking a paper ballot . . . if a human can mark it a human can read and count it.
when it comes time to tally the vote a machine does it faster, and probably more accurately, than a human.
recounts can also be done by using other machines to get a first look and comparing it to the count by a human panel . . . if there is a discrepancy, the source should be relatively easy to find.
[ when all is said and done, i worry more about masses of people (olds, non-whites, poors) being disenfranchised by the various cures for non-existent voter fraud ]
