Windows RT has the following desktop apps:
 
• Word

• Excel

• PowerPoint

• Outlook

• OneNote

• File Explorer

• Internet Explorer

• Powershell

• Control Center

• Device Center

• Windows Defender

• Remote Desktop

• Task Manager

• and some additional PC management tools

This should really be enough for a lot of power users. The file browser alone would justify the desktop mode. Keep in mind that with Windows RT 8.1 you can organize your SkyDrive files with a mouse.
