At the risk of sounding like a Microsoft shill, with the final release of IE7, I'm now switching from Firefox on my PC. Why? With most other features equal between the two browsers, there's only one relatively minor reason: The little "edge" beside each tab that, when clicked, opens a new tab.

I open new tabs frequently, and don't use keyboard shortcuts, so this saves me a whole second of clicking.
Moral of the story: Little things really matter in UI design. And for a UI designer, it's extremely difficult figuring out which little thing will matter most.
