This is a real nice web browser. It has a clean And efficient interface. It's also quite fast. I've tested it on numerous sites and the full desktop support works pretty well. There are some places where it just doesn't work at all, such as Yahoo Mail. Instead of giving you the desktop version, it gives you a stripped down mobile version of that site. However, so does every iOS browser that I've tried (except the original opera, which I miss very much)
I bought it for the zooming feature, which is the best I've seen on any browser for iOS. No matter what zoom level you choose, it automatically fits it to the page. This really does come in handy with websites that do a poor job of recognizing that you're on a mobile platform with limited screen space. This alone makes it worth the five dollars for me.
The only downsides I see for using zoomable As a primary or secondary browser are:
-bookmark importing is complicated. They use Json files. If you don't have a lot of bookmarks, this is not a big deal
-no search capability for bookmarks.
Looks like they do regular updates, so here's hoping they will consider this feedback.
