Reaction to 7 things about Google article

I just finished reading the article 7 things you should know about Google Apps.  It was striking that while written in 2008, many of the same things expressed here, match those that existed 3 years ago.  I did a training in the summer of 08 on Google Docs and wowed my students (fellow teachers) with the capabilities.  It was for many the first trip into the cloud.  The strength of Google made a compelling case for choosing it over other online services with similar features as Google is going to be around for awhile and they seem committed to an "anything you can do, Google can do better" mentality.  That still holds true.  The security issues and the concerns about letting go of data were their then and still persist for me and others.  The lack of trackability of what students are doing is also a concern.  Interesting that over 3 years, no clear cut answer has emerged.
