She would also like to see Google or its partners develop small applications for, say, tracking travel and expenses, as well as better integration between Apps and the Postini communications security and compliance platform Google acquired in 2007.

"If I can avoid leaving my Google Apps domain entirely to get 90 percent of what I need to get done, that would be helpful," Deshpande said. Mindcrest has almost 700 users of Apps Premier, which costs US$50 annually per user.

Above all, she would like clarity from Google about the future of Apps so that she can plan accordingly. "It'd be great to get a road map for the next three years," she said.

Others have pointed out that Apps lacks enterprise social-networking features that have become popular in competing collaboration and communication products, such as giving employees Facebook-like profiles and the ability to do Twitter-like microblogging. In fact, there have been rumors about Google being interested in acquiring Twitter.

There are also a number of Google consumer services that might be a good fit for enterprises, such as the blog publishing system Blogger, the Groups discussion forums service and Voice, an application for managing voice communications.
