Some further reading and testing with SharePoint 2007 has only increased my enthusiasm. Without having it all tested extensively, the new things I like are:

• The Recycle Bin: finally a way to ‘undelete’
• Bread crumbs: It’s a lot easier to understand where you are in a site
  
• Workflows: both to collect feedback and as a approval mechanism
• RSS support: see an example in my post of yesterday
• Project Tasks Lists with Gantt Charts
• Blog and Wiki support
