The vendor (Omni Group) provides the following description:
You're a Mac fan, right? When people ask you why you like the Mac, you probably think of the attention to detail that makes the Mac user experience superior. It's the sum of a lot of different things that add up to a system that's more powerful, more beautiful, and more fun.
What if you thought of a web browser in the same way? You use a web browser all the time, for working, for entertainment, for research; how cool would it be if every time you used it, you thought "Wow, this rules!"
Welcome to OmniWeb. OmniWeb elevates your web user experience to be more productive, more efficient, and more fun. You'll find information more quickly. You'll stay organized. You'll see the entire internet the way you choose. It's the browser that puts you in control.
Sure, you can use a standard web browser, with standard features. But you didn't choose a standard software experience - you chose the Mac. Why not try a browser built just for discriminating people with fabulous taste, like yourself?
