There are no shortage of office suites available for Android, but two of the most popular have been Quickoffice and OfficeSuite. The former took a hiatus after Google purchased it last year, and while the new version isn't bad per se, it's not what to used to be. In the meantime, OfficeSuite has continued to improve, and version 7.3 introduces a slew of new features that add an extra layer of polish to what is already a solid app.
If you use your Android device to do work, then a good office suite is absolutely clutch. And when it comes to such a tool, you'd be hard pressed to find something better than OfficeSuite Pro. It hit version 7 today, which brings along with it several new features and enhancements, including an improved UI, sidebar navigation in the file browser, templates, and extended cloud support to include Microsoft SkyDrive, as well as folder support in Google Docs.
