Google inc launched the new version of gmail for mobile. Sometimes its hard to believe we are trying this hard to please the consumers of free applications as developers.
There was a time when developers treated the free application market as a hobby something you do in your excess time and now we see the heavy weights fighting it out for the free applications. The free applications are as good or better than enterprise level applications.
So the only differentiation between a free application and an enterprise application is that a enterprise application comes with more fined tuned control for the enterprise while a free application is for a individual consumer.
Though something don't change much, years ago a company called gave operating system and software at throw away prices or free just to make it so part of a consumers life that it becomes a standard and then enterprises have no choice but to buy licenses for this application, a company called Google is dooing the same now.
I guess successful economics principles don't change much.
