I haven’t had a chance to test it out yet since I’m at work, but supposedly there is much improved support for USB and more importantly Mobile Devices running WM5!

The update, which is free for all Parallels Desktop users, includes several important upgrades, including:

• USB improvement, including USB support for Windows Mobile 5 and a much broader list of supported devices.
• The
  Mac hard disk cache can be now switched off for a virtual machine,
  which can substantially improve OS X performance while using Parallels
  Desktop.
• Improved graphic performance
  
• Complete keyboard support, including the “eject CD” button and right & left shift mapping for non-English layouts
• Unicode path support lets users name files and paths in any language
• Improved shared folders performance
• Minor bug fixes
