Visio 2010

Today I downloaded and decided to check Microsoft Office 2010 technical preview. While is too early to say anything about improvements in applications (I just installed it), there is one peculiar thing I noticed.

When installing Microsoft Visio you can go to customize screen to be presented with choice of installing Microsoft Outlook (trial) by default.

Why on earth would somebody install Outlook (selected by default) just because he is installing Visio?

I have no idea.
