Today, we live in the age of the Cloud. We don't worry about compression because Google Docs lives in a tab and Office 365 streams from the server. But there is a certain nostalgia for those 10MB .zip files that contained an entire productivity suite.
Using a "highly compressed" version of Office 2007 is only recommended for where modern software won't run. For daily tasks on a primary computer, it is safer to use free alternatives like LibreOffice or the free web-based versions of Microsoft Word Online which provide better security and modern features without the risk of malware.
