Microsoft Office Web Apps work better if you’ve Silverlight 3 installed; So how does Word Web App get better with Silverlight?

-Faster load performance, since typically fewer bytes need to be downloaded before showing the document.
-Improved text fidelity at 100% zoom. This includes better text spacing and rendering.
-Greatly improved text fidelity at other zoom levels not 100%.
-Text will respect settings set in cleartype tuner, so you’re able to determine how much (if any) cleartype you’d like to see. The -cleartype tuner is available on the web for older versions of Windows, and is included in Windows 7.
-Improved accuracy of hit highlighting in Find.
-PowerPoint Web App also benefits with Silverligth 3, for e.g. animations smooth out a bit, and the slide will scale with the browser window size.
