If you haven't checked out iWork yet, that is great for Word Processing, Spreadsheets, and Slideshows. iWork can handle all Microsoft Office files (.doc, .ppt, .xls), but Office can't handle iWork files (.pages, .keynote, .numbers). I have all of the iWork programs on my computer -- Pages, Keynote, Numbers -- and Keynote on my iPad. On the computer you can choose to save a copy of the file as an Office extension, but I don't think you have that option on the iPad since there is to file system. I guess the best way to use iWork would be to take advantage of iWork.com. As long as you have an Apple Account (what you would use to buy Apps from the App Store and Music from iTunes), then you can use iWork.com. iWork.com allows all invited viewers to read, edit, and download all files you load onto it. Check it out, it might be perfect for your needs.
