It's basically a skin over IE, but it has a lot better features like popup blocking, tabs, paranoia insurance, searches made easier, and so much more. In general it's a bit like building a castle on a mud pond, but the castle seems to stand up well enough on it's own.
It's also skinnable and has tons of pre-packed features like the afformentioned popup blocker and a flash save tool.
Try it out, it's a great IE replacement.
