Google takes an interesting standpoint on Office. Instead of claiming you should simply ditch Microsoft Office altogether and switch to Docs, Google assumes that most users already own a copy of Office 2007 or 2003. But, instead of upgrading to Office 2010, Google says, you should simply switch to Docs, which, in Google's eyes, is the perfect partner for one of the older versions of Office.
Google even created a comparison (see below) of costs and benefits of switching to Google Docs as opposed to upgrading to Microsoft Office 2010.
It's clever. After all, it costs you several hundred dollars to buy the new Office, while trying out Google Docs is free. However, I'm not completely convinced that Docs is at the level where it can replace Office (2007 or 2010) in everyday use, at least for professionals. What do you think?
