Apple and Microsoft interface guidelines

Today I found some time to look at the Apple Human Interface Guidelines for Mac OS X. Microsoft's latest guidelines are the Windows Vista User Experience Guidelines (still "preliminary documentation" though).

A few thoughts:

• The Vista guidelines are quite technology-driven sometimes, top rule number one is "Use the Aero Theme and System Font (Segoe UI)"
  
• Apple places more emphasis on the design process and stresses involving your users in early stage development and
  
• The Apple guidelines are clearer and easier to work with
• I really hope the final version of the Vista guidelines will be better

On first impression, Apple clearly wins. (And I'm not even a Mac user)
