Best school utility apps for the iPad

First published just a year ago, Oct 2010, I still rank all of these highly.

• GoodReader - file management
• Quick Office - word processor, spreadsheet, file management (alternative to Pages and Numbers)
• iThought HD - mind mapping 
• PhotoGene - photo editing
• Dropbox - cloud based storage, on mobile and PCs too
• Evernote - cloud based notes, audio, images storage and management, on mobile and PCs too
• Pages - Apple's word processor
• Numbers - Apple's spreadsheet

Updates: 

• with iOS 5 and iPad 2, anything on the screen of an iPad can readily be projected (see Apple TV)
• The need for image editing is reduces with basic editing now available in Camera Roll
• with iCloud, there is less need for other online storage systems.
