Going from one monopolist to another

Google is offering Office productivity tools in de cloud through Google Apps. To my knowlegde they are the only one with such a rich online solution.

When more and more people are going to use Google Apps, the suite is going to be a new standard. That will attract more users because it easier to exchange files in the same format.

And what about the "open-ness" of the Google Apps document format. Sure you can save a document in another format and then open it in that program (let say "Word"). But when you have edited that document with Word, you can not save it as an Google Apps document without trouble. You can upload the file as a new document, but that's not what you want. Also the layout of the document will be messed up...
I say: when you chose for Google Apps you are bound by it, as is the case with the choice for another office suite.

When Google has the biggest user base in the world, will they be not the next monopolist in the market?

Consider this:
The fact that all your data is on their servers is even more creepier.

With the offline Microsoft Office solution your data is still safe in your own network.

At the moment we use Google Apps only for "work in progress" and notes that must be shared or colaborated on.
The final documents and reports we still make and save with Microsoft Office (and Open Office although that causes compatibility issues). The files are safely kept under our own influence.
