Sometimes the fine print can actually save you money. Case in point: the latest copies of Microsoft Office. Many assume Microsoft wants money for every installation, but Office is technically licensed for at least two installations.
Windows site Neowin.net, by way of a Twitter reply from Microsoft's Australian offices, points out that every copy of Office allows for legitimate installation on one primary computer and a "portable device", which for all intents and purposes means a laptop. If your primary computer is a laptop, well, you're allowed to use Office on both those computers. Office's Home and Student version allows for three home installations, too, but that's another story.
So while reading through a licence agreement might seem like an exercise in migraine testing, scanning to the section on installation rights, or asking the question, can pay off. Because nobody around these parts was even thinking of making a secondary installation before being fully cleared by the licence agreement.
