It's quite interesting that a lack of resources ("given the small size of the design team at Acorn, a simple RISC chip was a practical choice") forced them to focus on simplicity. That simplicity then helped the chip use less power, which later left them well-positioned to capture a large share of a nascent battery-powered market.
