Here are some apps for iPad I recommend:


Social networking apps

Facebook - if you use it
Twitter - you NEED to use it!
HootSuite - I prefer this app over Twitter's for it's interface
LinkIn - if you are
Klout - if you have it
Pinterest - see more on this one here: Pinterest
Storify - you have to see this one! I love it for curating docs, videos, tweets, into an embeddable doc
SpringPad - like the next one - nice interface. You can share folder with others
Pocket - used to be called Read it Later - good for saving stuff to read later, and to organize it into folders - but you and do this in Evernote as well, which I like better!
Skype - yes, it does work!


Google apps

Gmail

Education apps

Edmodo - you use it, so get the app too!
eduTecher - about tech in education
Prezi Viewer - if you have kids do Prezis

Apps for text and doc prep:

Evernote - wow! I could go on and on about Evernote
Pages - best app for word processing in my view
Keynote - Apple's version of PowerPoint, only better (in my humble opinion!)
Numbers - if you need a spreadsheet
Penultimate - integrates with Evernote - draw, take notes by hand or with a stylus, draw pictures
Skitch - also integrates with Evernote - annotate pics and pdf files
