Currently tighter integration of Google's online office-style apps. with Salesforce's platform.
Notes how viral Google apps are spreading :
Much of this will happen under-the-radar. David Armstrong, product and marketing manager for Google Enterprise in EMEA, told me yesterday that Google Apps already has half a million organizations — not individuals, organizations — signed up worldwide, with 2000 more signing up every day. But that astounding adoption rate is visible only to Google. There are no shrinkwrap packages passing through distributors’ warehouses or flying off retailers’ shelves. There’s not even any money changing hands for sign-ups to the free version. It’s just an invisible stream of bits in the ether. Adoption will be mostly unseen, until one day it will suddenly have become too big to ignore.
Meanwhile ZDnet bloggers are tracking the fast evolving cloud / platform-as-service war.
