For me the history in my address bar is the most important thing. Switching to a new laptop recently and not bringing those across, I became painfully aware how much I use this. Often the reference page I care about, or a deep link into some tool is a few keystrokes (the first few letters of the service and deeper link). Bookmarks makes this info portable. It's like having close to O(1) access to the knowledge or tasks that are not immediately in your direct clickable range. Having extra non-title info makes this even better.
