This is a very philosophical debate,
that gets right at the root of the issue
of just how much should one consider enough
when it comes to tools and technology.
Email, if you don't go too far gratuitous,
for most people and most use cases seems to be quite sufficient.
But, these days due to the proliferation of tools,
specially as a result of a lot of the selfless good work
done by dilletantes on open source,
its become very easy to build an app
and seamlessly deploy it on the web very rapidly
through dev ops
and the cloud based infrastructure behind that.
Therefore, as a designer, you are left wondering
should I just leave good enough alone
or take the easy way out and make it even better.
That seems to be the 6 million $ ? at the heart of this post.
