Question

To explain why commonality is important, pcmag reminds us how the 2000 Presidential election was affected by apparently confusing punch cards in Florida. In that scenario, the interaction of humans with technology failed to prove consistent and resulted in a recount that cost time, effort, and money. A common user interface regarding ballots in all US polls might have been less stressful. Please describe other real-life situations where a lack of computer commonality can be detrimental or situations in which commonality could provide improvements. Be sure to comment on your peers postings as well.

Let us know what you have come up with so far -- then maybe someone here can help you think of others.

Thanks.
