I just got this in my email from out tech center (and indeed, I was able to download it for free):
There is a normally $11 app, that is free (likely today only) called Smart Office 2 that I thought some of you might be interested in. Here is more information if you are interested in it:
View, create, edit, and share Office documents with the productivity app. The app is loaded with features, including a variety of formatting and font options, preloaded templates, search, AirPrint support, the ability to export files as PDFs, and Dropbox and Google Docs integration. It also supports a wide variety of file formats.
Get it at the iTunes Store or from the App store on your device.
