ZOHO's online SaaS products are looking ever more amazing by the day. At a technical level they are a legitimate competitor to Google. M$ probably doesn't come close with it's Office Live suite, but they'll probably get somewhere eventually with their "keep trying" mentality.
I'm using ZOHO CRM, and can't deny a definite improvement in my sales data organization, as well as productivity. This will be my choice of CRM tool.
I'll stick to Google Docs for now for historical reasons, in spite of superior functionality that's appearing on ZOHO.
