CloudOn will be catnip for business execs on the go. It provides a free, cloud-based version of Microsoft Word, Excel and PowerPoint on your iPad. With CloudOn and a free Dropbox account, you can create and edit files native to all three Office applications. It's as if your desktop apps have magically appeared on your iPad. Once you’ve finished your edits, the file is automatically synced with your computer’s Dropbox folder. In addition, CloudOn adds useful keys to the tablet’s virtual keyboard such as Esc, Del, Ctrl, Alt and all 12 function keys. Downsides: Because it's cloud-based, you must be online to work with your files, and rumors are the app may soon have tiered pricing.
