The issue was not that the touch-screen machines failed to work as advertised. The state encountered some problems along the way, but by and large, they did what they were supposed to do. (The bigger frustrations came from initial glitches with a separate system to check in voters at polling places.) The issue was that voters never fully trusted the machines because there was no way to verify that they registered your ballot the way you wanted it and no way to check whether the machines' tabulations were made in error. Reports this year that when some people attempted to vote for Republican candidates, the machine's display showed a check mark next to the Democrat's name probably were a result of voter error, as election workers contended, and there were no reported cases in which the error was not fixed before the voter hit "submit." But the fact that there was no way to prove after the fact that a vote had been counted properly magnified the anxiety.
