Some need total document compatibility with Office file formats others rely on features not yet implemented by Open Office. Love it or hate it, the fact is that Microsoft's suite of office software is a necessary part of many people's workflow.

'Play On Linux' may sound like a toy, but if you want Microsoft Office working on your Linux machine it's a seriously useful program to have around.
