The rest of the Microsoft Office in-the-cloud services
Two services let you run Office 2010 as a hosted app over the Internet from a Windows Server, with the claimed benefit of giving you the actual Microsoft experience on your iPad.
Microsoft's free, hosted Office Web Apps works surprisingly well in the iPad's Safari browser but has little integration with the iPad. Accessing local files or printing requires labor-intensive workarounds. (Log in from office.microsoft.com.)
The free OnLive Desktop is a horrible Office hosting service: It scrunches Office 2010 into the iPad's smaller screen. The app forces you to manually activates its own onscreen keyboard, can't print, and loading files requires separate login to its website. Plus, leaving the app disconnects you.
