I procrastinated for nearly two weeks before installing Microsoft’s new Web browser. I’d been happy using rival products like Firefox and Chrome at work and Flock at home, and habits are hard to break, even though version eight of Internet Explorer, or IE8, has several promising features. In essence, all browsers have gotten so good at delivering the basics that I find little reason to change. The frills are what sets each browser apart, but getting unique offerings in one means giving up features in another.
