I've only been using the Ipad for a week, but I'm teaching two summer classes, so I'm putting it to use. I've been using the Gradebook EasyGradePro for about 10 years on my Mac laptops, and there's an app called Gradebook Pro that works pretty much the same way, so I've set two classes up on using that.
I've also been using Dropbox and Evernote as well as my iDisk to play with transferring lecture notes from my laptop to the iPad for editing.
I'm trying to learn the fine points of Pages, and so far like it.
I've also been trying Quickoffice, and the Word Processor seems fine, but I've been having trouble getting it to connect to my iDisk, so haven't used it that much. It connects with Google docs and Dropbox just fine.
I've been trying PrintCentral Pro, but I'm not real happy with it--it works, but I'm getting only the page that appears on the iPad screen. I probably just need to tweak the settings.
I'm also doing a great deal of writing using Pages--I find an external keyboard crucial for this. I haven't really worked with putting things in APA or MLA format yet, but I'm guessing it won't be too hard.
I've found it incredibly useful for lectures and writings to have my MacBook open in Safari to use Project Muse or JStor to call up articles or to use Google to get some information and then be able to write with the iPad right next to the MacBook--talk about efficiency and saving time.
Good luck--I'm new too, so I'm following this thread with great interest.
