Office 2003 appears to be falling behind in targeted sales for this point in the product’s lifecycle, according to Microsoft’s own internal figures and guidelines. Just 15% of PCs are running Office 2003, two years into its life, with Office 12 – the next edition of Microsoft’s ubiquitous suite – now on the horizon. However, Microsoft traditionally expects between 50% and two thirds of customers to be running the previous version of Office when the new copy ships.
