If it weren't for Parallels Desktop, the virtualization product for Intel Macs that lets you run Windows alongside Mac OS X, many working Mac professionals would be forced to carry two laptops. So it's good news that the Mac's most popular method of running Windows within OS X (the other, less effective, method is VMWare) recently sprouted a few really useful enhancements:

• Parallels' Coherence feature, which lets you use Windows application windows within OS X instead of in a Windows "box", now supports Expose, OS X's zoomed-out, view-all-windows mode.
• Macintosh folders can now be mapped to Windows/DOS drive letters to cut down on navigating (before you had to create a network place).
• Virtual Machine hard disk images can now be mounted to the Mac OS X desktop.
  
• Windows windows now have OS X drop shadows in Coherence mode.
• The iPhone can be synchronized with the Windows virtual machine.
