Google announced that its collection of applications, Google Pack, now also includes StarOffice. This application is an office suit developed by Sun.
StarOffice 8 is a full-featured office suite that contains a word processor, a spreadsheet tool, applications for presentations, databases, math formulas and drawing. It has support for most Microsoft Office formats (except for the formats introduced in Office 2007), but it can also export documents as PDF out of the box. The software normally costs $70, but it's available for free in Google Pack. It's worth noting that StarOffice has a huge installer (more than 140 MB), so you should download it only if you have a fast Internet connection.
It will be interesting to see why Google didn't choose to include OpenOffice.org, the primary difference between StarOffice and OpenOffice.org being that StarOffice includes some proprietary components like clip-art graphics, fonts, templates and tools for Microsoft Office migration.
