Because they are web based that means you have Office on Mac, Linux and whatever else can run a popular browser. Microsoft also throws in 25GB of FREE storage.
Another feature that is unique to web apps is the ability to SIMULTANEOUSLY edit documents by 2 or more users at one time. For example, 4 users can have an Excel spreadsheet open and be editing it and the other users will see the updates in near real-time (my experience is in about 2 seconds). OneNote also allows simultaneous edit, although I've noticed a much longer update interval (about half a minute). Word currently doesn't appear to support more than one user.
For some reason my embedded video demo of Office Web Apps is not working. If so, just click here to see video demo.
Office web apps are limited in features--but still very useable. Here is a list of some of the limitations that I noticed:
Word Web App: No multi-edit,
Excel Web App: No printing, no chart creation
PowerPoint Web App:
OneNote Web App: No printing, No Search Feature
Some very great points about Office Web Apps:
-Office on Linux and Mac
-Host Office Documents You can link to: Click Here to See a Word Web App Doc.
-Access Your Docs Anywhere
