Atomic Web Browser - Full Screen Tabbed Browser w/ Download Manager & Dropbox. iCab Mobile (Web Browser) Fullscreen Video and Browsing From iPad HDMI. This app has excellent uses in education and more specifically in the classroom.
I can think of a dozen reasons why this would be useful to a teacher. The offline tabbed browsing and file download features are really good but the ability to share your iPad screen over a HDTV is what really opens this app to the education sector. This is especially true for those schools that still do not have data projectors in every room. It is an app that certainly gives us another option anyway!
