"I am a long time user of the Palm OS version of DataViz's Documents to Go, and was happy to hear that DataViz makes an Android version I can use on my T-Mobile G1. This lets me work with Microsoft Office documents, including ones that come in as e-mail attachments.There is a free version available in the on-device Android Market that allows you to view Microsoft Word and Excel documents. For creating or editing Word, Excel, and PowerPoint files, or viewing PDF files, you need the full version.If I need to work on documents while I am out of the office without using my laptop, I generally copy the files via USB to my G1. I can access them through Documents to Go.When you open this application, the home screen has four icons, one each for Word To Go, Sheet To Go, Slideshow To Go, and PDF To Go.When you select the icon for the file type you want to open, you are given three ways to open a document. You can select "Open File" which opens a browser window to browse to the file, "Create New Document", which will then open a blank document, or you can select from the recently used list."
