The publicity on the website promises faster screen refreshes and page-loading. And claims to offer Flash functionality. I tried it out on a few sites where I cannot use my iPad and was pleasantly surprised. Puffin even includes a virtual pop-up trackpad so you can use a pointer to click and scroll on sites that don't like the touch and swipe UI. There are a few idiosyncrasies, but overall I was impressed with what it can do. Try it with your favourite edu site.
