If you have'nt tried Orca Desktop app (in Beta), you probably should give it a try. It is a well implemented virtual desktop application. You can try it here. [login as demo/demo]

Orca folks integrated Zoho apps into their desktop. You can launch Zoho Writer and Zoho Sheet from their Virtual Desktop. This is a good first step integration. Here is a screenshot.

 

Looking forward for more such integrations.
