Hi - I asked a similar question the other day and was very kindly assisted by this site. You can use cloud on which is a free app and store everything either in Dropbox or google equivalent for it to sync. When you open on cloud your documents are there for you to change. I haven't as yet printed or used not with wireless available as I'm pretty new to the world of iPad and only just discovered it. Functionality is pretty good though. Other than that you have Apples Pages but it's £6.99 and the same again if you wanted numbers which is similar to excel. Cloud on has word, excel and PowerPoint. Not sure if this helps but this site will definitely assist you. Cheers. Dawn
