"Here are three alternative browsers that I use regularly to perform tasks I think are necessary for educational use and general use that I can’t do using Apple’s default browser."
KF: Summarising this article:
iCab - Quick, allows video download, multi-search engine access, some social media integration.
Diigo Browser - utilises Diigo tools - annotation, bookmarking, etc. API integration with some web favourites. FREE
Photon - handles Flash sites. Pricey. (Check out Puffin and iSwifter too if you're looking for some flash capability via the iPad.)
