Is it possible to survive only on Google Apps?

Since moving more and more of our work onto cloud computing, in particular using the growing Google suite of applications I'm now in a position to see if it really is possible to live without MS Office.

So from Monday I'll not to use any MS Office applications to see if it really is possible to use nothing but the free tools in the Google Suite - Gmail, Google Docs, Google Sites, Blogger, Chrome and the various small tools that come in handy. On paper it's certainly possible but I want to know if it is a practical proposition for us mortals.

I can already see a couple of challenges. The first one is that Google Tasks isn't really integrated with anything apart from itself. Synchronisation is clumsy and I'm not sure if it will handle contacts properly. That might seem unimportant but I'm mobile during the day and if it won't go in the backpack it doesn't come with me if I'm on the pushbike around town. So reliable syncing with my mobile phone is vital.

That's enough for now, let's see how it goes.
