Although it is a nice feature, for me the most important Chrome feature is unifying the address and search box. Even non-technical people know to respond to a software update prompts, but the number of people I see (including normally quite tech savvy people) that still search for a url, or enter a search in the address field surprises me. OK, you could argue it is bowing down the lowest common denominator, but I believe it's a great feature that saves the frustration of people that just want to do go somewhere or find something on the web quickly.
