I’m looking into buying a tablet and am therefore of course looking at the various iPad models. I know that iPad Pages, Numbers, and Keynote can be used to open and edit Word, Excel, and Powerpoint documents. It is my understanding that Pages, Numbers, and Keynote created on your iPad can also be saved as Word, Excel, and Powerpoint files. Is this true? Also, can you access the iPad Pages, Numbers, and Keynote apps if you are unable to access the internet? And, can you save Pages, Numbers, and Keynote documents on your iPad (or a USB) when you don’t have internet access?
