Microsoft has been enthusiastically rolling out touch-friendly Android (and iOS) versions of Office, even before it launches on its own OS. It just outed a preview version for Android smartphones, although this time, Windows did get it first. As with the tablet version, Microsoft said the apps marry the "familiar look, feel and quality of Office" apps -- including Word, Excel and PowerPoint -- to a touch-friendly smartphone experience. You'll be able to open documents not only from Redmond's OneDrive, but also via Google Drive, Dropbox, and a few other cloud services.
