Adobe Unleashes Acrobat.com, Takes on Google and Microsoft

«About one year ago, Adobe created tools for building documents collaboratively online: Acrobat.com. Not to be confused with the desktop version, Acrobat.com is meant for business collaboration, similar to Google Docs.
Now a full year later, Adobe is turning up the heat on its competitors with a series of big announcements. First, Acrobat.com is coming out of beta. Second, business subscriptions are going live. And third, it’s releasing an advanced tool to build spreadsheets, on top of the Presentations program it released last month.»
