I'm currently in a developing nation, unable to buy much variety of goods or services, and keenly aware of just how incredible it is to be discussing fractional seconds of transaction time for something that is – for me currently – either 1) several weeks of very expensive shipping away or 2) requires sending someone to the capital to train in the expertise.

I don't mean to dismiss the attention to microseconds (I'm an advocate for continuous improvement, after all)... I'd just like to share this fresh/broad perspective.
