I’ve been using and advocating free software for around six years. When studying and then working as a freelance writer, migrating an office seemed so simple — draw up a list of comparable programs and, over a reasonable period, move your staff across. But over the past few weeks I’ve been trying to use Ubuntu Gutsy on my desktop PC in a Windows-based office, and whilst most things work just fine, it’s far from the seamless integration I was hoping for.
