Still waiting for Microsoft to release Office for the iPad? Don't bother. Here's another app that fits the bill, and it's free.
Released in November for the iPad, HopTo lets you view, edit, and create Word documents and Excel spreadsheets, and view PowerPoint presentations. You can access and edit those and other types of files from your local computer and from Dropbox, Box, and Google Drive. And thanks to the latest update, you can now tap into your Microsoft OneDrive files.
