I've read many of those same stories. Probably the best analysis I've read so far is on Sam Wang's site at Princeton. He doesn't dismiss the possibility of fraud, but he does feel it's unlikely that there was enough fraud to throw the election. Also, for what it's worth, I think the best summary of where we need to go from here was in an editorial in yesterday's NYT. So many different things went wrong in this election. It's not just about voting technology. It's about the entire process, top to bottom.
