Portable OpenOffice.org is the to-go version of OpenOffice.org, sporting the exact same functionality, with the upper advantage of a standalone deployment, leaving the computer configuration and the Windows registry untouched.
OpenOffice.org is an Apache product, aiming to provide a full-featured document processing suite that can easily replace paid software such as Microsoft Office. It comes off as a multipurpose collection of tools oriented towards a wide array of audiences such as home users, schools, businesses and governments.
The suite includes a palette of utilities that can deal with word processing, spreadsheet editing, presentation design, databases and graphics, to name the most important of its tasks. More importantly, it sports undeniable compatibility with Microsoft Office formats, facilitating the migration to OpenOffice.org.
The suite includes six distinct components, all of which can be launched individually. Writer is a utility similar to Microsoft Word, which allows users to create and edit documents, as well as web pages.
Analogous to Microsoft Excel is Calc, which is able to deal with spreadsheets. Impress is a program that builds an exports presentations, much like PowerPoint, while the Draw component edits vector graphics, similar to early versions of Visio.
Microsoft Equation editor can be easily replaced by Math, a program that manages formulae, whereas Base deals with databases, just like Microsoft Access does.
Nonetheless, the suite does not provide an equivalent for Microsoft Outlook, which may be for some users, a deal breaker. However, its predecessor, StarOffice provided such an alternative, but the feature was removed, for unknown reasons.
This disadvantage aside, Portable OpenOffice.org is robust, stable and efficient. It covers the needs of home users and small to large business. The portable approach is often preferred because it can be carried around on a removable drive and launched on any computer without altering its registry settings.
