Looking back, it’s obvious that one titanic struggle has loomed large over the SaaS and cloud landscape: the battle for your email.I give Google kudos for getting its name into the top 3 e-mail vendors. Consistently in 2009 when I asked enterprises and SMBs about their e-mail vendor choices - without going into delivery models, costs, operations, and risks - the top three systems were listed as Microsoft, IBM, and Google. Since GMail's beta release in April 2004 and general availability in early 2007, Google has become a leading e-mail consideration. That's powerful stuff.
I agree that collaboration is the stuff the web was made for. Should be an interesting 2010.
