This is another key component in Google's strategy to create a suite of products capable of real traction in the corporate marketplace - and that will make them money and (incidentally) cut way into Microsoft profits.

Now as a start-up - are you wasting money running a host of "internal" support software or are you using what is out there and freely available? The latter of course, because what matters is what you are building. Well that's how it is gong to be soon for a lot of businesses who have "made it" - they are not going to waste money and (perhaps more important) management time running their internal support IT functions. Yes they will run ERP systems but why get tangled up with office software/email/Intranet etc. etc.
