One of the engineers on my team shared an interest in Human Computer Interaction (HCI) this week; Two days later, and before I could action resetting on the subject, I came across this post that opened my eyes to how Steve Jobs and Apple's original vision for personal computers was a stake in the ground for HCI. Serendipity.
