Let's get the preliminary question off the plate first: who is Matias Duarte? Well for one thing, he oversaw the designing of a few small projects such as webOS, Sidekick OS, and Helio (the little carrier that could... be bought out). And, oh yeah, he also played a large part in Honeycomb's development.
Yesterday he sat down with Joshua Topolsky of This is my Next (soon to be The Verge) to discuss the "philosophy" of Android and, more specifically, Ice Cream Sandwich. It certainly provides some interesting insight into the man behind ICS' fancy new UI, and while we highly recommend you read the full interview, we'll be providing a few highlights below so as to save you some time (the unabridged version is quite lengthy).
