I get asked what's new in Vista, or why is it better than Windows XP quite a bit, the trouble is, there's just so many new or improved features that make it better than Windows XP. So from now on I'll be recommending this:
If you want to know what's new in Windows Vista, there's nothing more in-depth than the Windows Vista Product Guide. Available as a 61MB Word file or 25MB XPS document.
For those using Word 2000-2003 make sure to download the Office Compatibility Pack to enable them to open the new Office 2007 XML file formats.
